When a bat is made out of a hard material, it allows the bat to transfer more energy to the ball when it is hit, enabling the ball to move faster and farther. A great way to keep a rhythm throughout your swing is to step or stride toward the pitcher. There is no set formula. /V 21 0 R When To Know Its Time To Replace Your Baseball Mitt, Customizing Your Baseball Bag: A Guide To Personalizing Your Equipment. /P 14 0 R The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. The first is where the bat feels best in your hands when you hit. endobj According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . The first is where the bat feels best in your hands when you hit. Some of the numbers change with actual speed, but the physics doesnt change. This minimises discomfort to the hands caused by vibrations excited by the impact. Why? The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. >> >> If there was no loss of energy during the bounce then COR would be 1.0. The bat and the forearms are locked at right angles at the beginning of the swing, by locking the wrists, otherwise the bat would start to rotate in the wrong direction at the beginning of the swing. The reversal of the spin in each bounce implies that there is some tangential elastic behaviour of the ball in a direction parallel to the block. The collision of a bat and a ball can be understood by treating the bat as a heavy ball whose mass depends on the impact point. Hit the ball at this spot, and the least amount of vibration will travel throughout the bat. endobj /Length 996 Published Mar 30, 2018 4:11 PM EDT. A baseball bat is shaped in such a way to have a "sweet spot." The sweet spot is due to the fact that the CP and the VN coincide. The bat was swung through an angle of about 30 degrees to strike the ball. Collisions.- 11.Bat Performance.- 12. When a very light bat is swing velocity at maximum, it has little power to transfer to the ball. It is not difficult to swing a bat. A pitch produces a turbulent wake of air behind the ball. For the purposes of this paper, I will attempt to examine the . Ball Trajectories.- 4. The impact on a baseball bat is shorter (since the bat and ball are harder or stiffer), about 1 msec. So, well hit balls are struck at the sweet spot. However. If the ball is also mounted as a pendulum, the experiment can also be performed in reverse, by swinging the bat at a stationary ball. Demonstrating the sweet spot of the bat in a talk I gave at Wrigley Field for University of Illinois alumni in 1997. The material of the bat can affect its performance, as lighter bats tend to be more responsive and have higher exit velocities. ); q is also called the apparent coefficient of restitution or ACOR. The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. << The force on the bat can be worked out from the velocity of the center of mass, (CM), and the torques can be worked out from the angular acceleration. The force of the swing is also a key factor in the performance of a baseball bat, as a hard swing can generate more power, while a softer swing can produce more control. Both papers can be downloaded. Reflexes. /Width 77 The heavier the bat, the higher the bats bat speed. /P 26 0 R Potential energy is what might be called stored energy. When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. Some hoop mode sounds are recorded in the following QuickTime Movies, using an aluminum bat and several aluminum tubes of various diameters and wall thickness. You can actually hear where the sweet spot is just by tapping a bat yourself. A bat is similar to a racquet but there are some obvious differences. As discussed earlier, missing the sweet spot can cause vibrations in the bat. The bat breaks when large amplitude vibrations reach the thin part of the handle. First and foremost, we develop a simple but effective theoretical model to give a rough estimate for the sweet spot of the bat. A high performance bat has a strong trampoline effect and hence a relatively large COR. The tangential COR is defined in the same way as the normal COR, but in terms of the horizontal speed of the ball at the contact point rather than the normal (ie vertical) speed of the contact point. Strike at 12 cm Strike at 17 cm Strike at 24 cm Strike at 31 cm. Through its shape, weight, and material composition, a baseball bat is designed to maximize a players power and accuracy while theyre at the plate. << /N 12 0 R By coupling the flexible bat to the ball via a parametrized fo. The ball rotated more than 1/4 but less than 1/2 of one revolution from one frame to the next, each frame being 0.04 sec apart. I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. Experience. 19 0 obj callback: cb If the ball is struck at the sweet spot of the bat, then the batter feels almost no effect at all. In fact, if the ball strikes the bat exactly on the ``sweet spot'' then the hitter is almost unaware of the collision. The idea is to mount a bat as a pendulum and strike it with a ball at various spots along the barrel. The lines behind the bat, passing through the axis, mark out angles of 5, 10, 15, 20, 25 and 30 degrees. Nathan hopes to test the theory of Robert Adair, a Yale University physics professor and baseball guru, who believes the subjective sweet spot sits on the node where the bat's lowest frequency vibrations drop out. As a result, the fundamental and second vibration modes are both excited with about the same amplitude. Theres one where it feels good in your hands, one where the ball comes off the fastest. 2 0 obj The softball bat will vibrate mainly because it either hitting or missing the sweet spot. This cookie is set by GDPR Cookie Consent plugin. But its not that simple. The following material has been expanded considerably into a 324 page book Physics of baseball and softball published by Springer in March 2011. Wood bats and aluminum bats have their own set of advantages and disadvantages, and the choice for the player is based on preference. The second definition is where the ball comes off the bat fastest. endobj READ SOMETHING ELSE Table of Contentsshow << When a player has a bad hit and fails to hit the sweet spot, it causes vibrations which can cause the bat to bend or break. Share your thoughts with us below! It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. Different materials have different natural vibrational frequencies, and depending on how large or small the waves are, there are nodes at evenly spaced intervals along any object where it wont vibrate at all if struck. It has been found that the swing speed for any given batter is proportional to 1/(Swing weight)^n where n is typically about 0.27 for most batters. For example, a 33-inch bat with a -3 rating weighs 30 ounces. stream How do you find the acceleration of a system? For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. the location where maximum energy is transferred to the ball. hitting a baseball is either painful or frustrating. Aluminum bats are believed to have longer sweet spots than wooden bats. endobj endobj It is also known as the weight to length ratio. /R [316 73 572 791 ] Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. The sweet spot is typically located around the center of the bat, and its size varies depending on the type of bat being used. This cookie is set by GDPR Cookie Consent plugin. /V 16 0 R 9 0 obj And we divide that by Pi times 9.00 centimeters written as meters so centi is prefix meaning ten times minus two and we square that diameter. >> The following three movies show a batter swinging three different bats as fast as possible, filmed at 25 frames/sec. Each type of wood has its own unique characteristics, making it important for players to consider the type of wood when selecting a bat. Baseball players obsession with bats is second nature to them. When selecting a bat for the major leagues, it is critical for players to select the best wood for their bat in order to maximize performance, durability, and longevity. The physics of the three sweet spots of a baseball bat is discussed and the location of the ball impact point on the bat that leads to maximum ''power'' (greatest batted ball speed) is determined. The hand moves forward faster than this in practice, so the spin rate could easily be around 1500 rpm. Magnetism is also an important aspect of baseball because bats use magnetite, a magnetic substance found in the body, as a means of internal navigation. It would therefore not be surprising if a softball can be pitched at say 1000 rpm. << Hence, there are two vibration nodes in the barrel. /R [52 73 308 791 ] What is velocity of bullet in the barrel? Although the Hickory bat wood is the most difficult to swing, it is also the most powerful, making it the hardest of all bat wood species. Any two connected segments can be analysed as a double pendulum. 2.1. Their sweet spots are anywhere between 10.16 and 25.4 cm from the barrel end. { Physics; Physics questions and answers; A baseball bat has a "sweet spot" where a ball can be hit with almost effortless transmission of energy. If the bat approaches a ball incident at speed vin then. Necessary cookies are absolutely essential for the website to function properly. | /P 23 0 R The wake gets deflected depending upon which way the ball rotates. The weight drop of a baseball bat is the difference between a bats length and its weight in ounces, which is the difference between a bats length and weight in ounces. If you hit . But how does a batter do it? The majority of hitters take a stride when hitting, which helps the timing of their swing. The sweet spot is found on only one side of the bat. The cookie is used to store the user consent for the cookies in the category "Analytics". There is no simple physics answer to the heavy/light bat question here. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. Join PopSci+ to read sciences greatest stories. A bat with an end loaded weight indicates that it weighs between 30 and 28 ounces. The ball also generates potential energy through the bat, resulting in a powerful, far-reaching hit. Neither the CoP nor the 'sweet spot' maximises the velocity which the ball gains from the impact. How Many Square Inches Of Orange Does It Take To Cover A Baseball Cap? Licensed under CC BY-SA 2.0, via Flickr Creative Commons. Well also examine the impact that technology has had on the design of baseball bats in recent years and how it has helped players to hit the ball farther and harder. Each impact was recorded on a video camera at 25 frames/sec. The ball is spinning clockwise before it bounces and hits the granite block with backspin. This equation for acceleration can , Dry ice is the name for carbon dioxide in its solid state. (The first person to really investigate sweet spots did so on tennis rackets.) 2) Choose the right turn model As discussed earlier, a wider handle will improve bat durability and reduce the likelihood of breakage. Sign up to receive Popular Science's emails and get the highlights. The result: a harder-hit ball. There is a difference between a bat and a racquet here, in that tennis strings are very light and give back to the ball 95% of their stored elastic energy. He received his Ph.D. in physics from the University of California, Berkeley, where he conducted research on particle physics and cosmology. . Thank you so much for. The length and weight of a bat is tailored to the size, strength and hitting style of the individual player. Most people find that an impact between the nodes of the first two modes (node1 and node2 in the diagram) feels best since both modes are then excited only weakly. >> The fundamental mode of a wood bat has a node located typically about 17 cm from each end and a frequency typically of about 170 Hz. In any collision, energy from both objects gets transferred around, but in a swing your goal is to put as much energy as possible back into the baseball. Boxing. There are some models that include oak, but it is not as popular as maple or ash. << The 232 g bat was swung at 45 radians/sec on average (by the batter in the film). How is this described in Mechanics? /N 27 0 R When you hit a ball just right, you've hit it on one of the three "sweet spots" of the bat. By maintaining the same swing speed with a heavier bat, players can increase bat speed and distance in the same manner. endobj /Title (Untitled) Similarly, an impact at the node of the second mode will not excite the second mode but it will excite the fundamental mode. Balls compress along the same F vs x curve, regardless of the ball speed, although the actual compression curve for a given ball will depend on its stiffness. This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. Impact at 2 cm Impact at 7 cm Impact at 12 cm Impact at 17 cm, Impact at 24 cm Impact at 31 cm Strike at 2cm Strike at 7 cm. /R [316 73 572 791 ] Not exactly like a drum, more like a bell or a chime, but the effect is similar. << Physics 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. @L`YKUJNGBP\poR=_;Dl'P(T Where is the Sweet Spot on a Baseball Bat? However, it will also feel heavier when swung. On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. Sara Chodosh /P 17 0 R Metal bats, on the other hand, are lighter and more forgiving, but they lack the power of iron bats. The direction of the centripetal force is toward the center of the circle followed by the path of the CM. << Choosing the right wood is essential for the proper performance of baseball bats. These cookies ensure basic functionalities and security features of the website, anonymously. By understanding the physics of baseball bats, players can maximize their performance on the field. It minimizes vibration of the bat and results in the maximum energy delivered to the ball, meaning it travels the farthest. << So, after a rainy day game, ensure your bat is dry before you store it. Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. The impact of a bat and a ball is still not properly understood. Explains that a baseball bat's "sweet spot" is approximately 17 cm from the end of the . Otherwise, the effective mass of the bat is less than its whole mass. If the bat is at rest then we can define the ball speed ratio, Bounce Factor = q = (ball exit speed) / (incident ball speed). A hollow aluminum bat sounds a lot different to a solid bat since the wall of a hollow bat can vibrate in and out like a drum. When a pitch is played, a turbulent stream of air runs behind the ball. This website uses cookies to improve your experience while you navigate through the website. If you drop the weight, you will be able to use the bat with greater control and power. 15 0 obj As a result, the bounce is relatively weak at the tip and near the center of mass. 5P8$ BaPR+"dUkbQ]YH`P. Edd Roush holds the distinction of being the heaviest Major League Baseball player in terms of weight. Uncovering The Mystery Behind The Golden Glove Award What It Takes To Receive This Prestigious Honor, How To Restring A Rawlings Baseball Glove Web: A Step-by-Step Guide, Exploring The Meaning Behind The Phrase Peanut Butter Jelly With A Baseball Bat. Energy is lost during the collision if the bat vibrates. An example of data being processed may be a unique identifier stored in a cookie. 9-d\DA=cZ0Q>gIM$$;cd2O@&a;X,Nn_aP(]I1aRc(K1^ue> A good power hitters bat is an end-loaded one, which allows the player to hit the ball farther. /WhitePoint [0.9505 1 1.089] The batter might find that he needs to change the way he swings the bat if the swing weight is altered, or he might have a grooved swing technique and swing every bat the same way. The node sweet spot differs from the center of percussion sweet spot. It is not difficult to swing a bat. The ball rotated more than 1/4 but less than 1/2 of one revolution from one frame to the next, each frame being 0.04 sec apart. On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. The effect is known as the "trampoline effect". 13 0 obj Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. } It is critical not only for the sake of performance, but also for the sake of safety. There is a significant difference between end-load and balanced softball bats in terms of weight distribution. /ColorSpace [/Indexed /DeviceRGB 255 28 0 R] The frequency is typically between 1000 Hz and 2500 Hz, meaning that the wall vibrates in and out 1000 to 2500 times in one second. While the center of mass moves one way (nearly upward here), the handle moves the opposite way (nearly downward). Dont store your bat in your garage or trunk of your car, bring it inside. Understanding the sizes of bats is critical to making the best choice for your game and the best bat for you. This includes both the length of the barreltop part of the batand its diameter The longer the barrel, generally, the larger the sweet spot for hitting the ball The standard diameter is 2 , and big barrel bats, allowed in some leagues, are 2 5/8. We offer our conclusions in Section 6. These cookies will be stored in your browser only with your consent. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. Specifically, what forces and torques are exerted on the handle, and in what directions do they act? /N 10 0 R In recent years, an acoustics professor and engineer, Daniel Russell, from Pennsylvania State University helped, Bat-Ball Science Mass Moment of Inertia article, The Science Behind Breaking Baseball Bats, Characterizing the performance of baseball bats, Performance versus moment of inertia of sporting implements. Although playing a game of cricket requires a significant amount of time, it is filled with powerful and fast forces. Since F = m*dv/t, we can integrate the force waveform to measure ball speed vs time, then integrate v = dx/dt to measure the shift in the ball CM vs time. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. The science of magnetism, while not as well-known as the science of moving energy when a bat hits a ball, is still important in the game. window.mc4wp.listeners.push( 21 0 obj The bounce was filmed at 300 fps and is played back at 30 fps in slow motion. Furthermore, the tip is the lightest and least effective part of the bat. You can find the sweet spot by gripping the bat handle with one hand in the same place as when youre swinging. How do you know if a bat is too heavy for a boy? 6 0 obj Youre already losing about half the balls energy to deforming it (baseballs squish down to half their diameter as they impact a bat). Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. A superball has a COR of about 0.9, a baseball has a COR of about 0.5 and a sorbothane ball has a COR of about 0.1 (ie it hardly bounces at all). << /R [52 73 308 791 ] They can change their flight path after being exposed to different magnetic pulses, and scientists have discovered that big brown bats can adapt to these magnetic shocks. During the fraction of a second after the ball hits the bat, the ball compresses as the energy of the motion is absorbed by the ball, causing it to become elastic potential energy. Batters know from experience that there is a sweet spot on the bat, about 17 cm from the end of the barrel, where the shock of the impact, felt by the hands, is reduced to such an extent that the batter is almost unaware of the collision. Most contact and power hitters use maple bats because the material is the strongest and has very little give, which is why they swing ash bats. The sweet spot's location for maximizing how far the batted ball travels after being hit can be calculated scientifically. The batter needs to exert a small couple to get the swing started, using equal and opposite forces on the handle, otherwise the barrel of the bat will get left behind. Elastic behaviour in the horizontal direction can be described by a tangential coefficient of restitution, which is about 0.5 or 0.6 for a superball but only about 0.2 for a baseball on a rigid surface. Typical results are shown here for a superball, a baseball and a sorbothane ball. When the ball hits the sweet spot of the bat, the hand-held end of the bat should come to halt without receiving any impulse from the hand. So grab your bat and lets dive into the science behind the swing! Adding to that is the fact that bats have narrower handles than in the past which makes the bat less sturdy and more prone to breakage. /R [316 74 572 585 ] The mode shape of a baseball or softball bat is a simple flexing bending shape that has parts that move and parts that don't. Every bat has a point about seven inches in from the tip of the bat that doesn't move, that doesn't vibrate, called a node. Baseball is based on the principles of Newtons laws of motion. << } Although most baseball players may not know the deep details, they usually understand that it is not just the skill and effort they put into their swing, but also the specifications of their baseball bat which will impact the success of the hit. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. I have done quite a bit of independent research in both areas. A batsman during a cricket game aiming his shot to hit the sweet spot of the bat. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. Check out Sniper Skin's easy to install, weatherproof and dural bat grips here! The whole mass of the bat is not involved in the collision, unless the collision happens to occur at the centre of mass of the bat. Are you a fan of composite or wood? 28 0 obj Hitting the "sweet spot" is something that baseball players strive for. Newtons second law, which deals with the value of time, is also important in baseball. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. The shoulders reach maximum speed first, then the upper arms, then the forearm and finally the bat. I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. The Physics of Baseball. When you hit the sweet spot, the bat feels the best in your hand. Aluminum bats are hollow so the distribution of mass is very different than a wooden bat, which makes it much easier to swing the bat and therefore produces higher speeds and more powerful hits. But I would expect there to be a difference.. Adair provides a few answers in his book The Physics of Baseball but he does not give the directions or the torques. A ball that strikes the bat does not cause it to vibrate at this point. External forces are the only way to redirect the ball according to the first law of motion. Near the end of the swing, the bat swings so fast that the batter can no longer keep his wrists locked, and the centripital force on the bat is about equal to the weight of the batter. In practice, batters tend to prefer bats that are lighter, rather than more powerful, since lighter bats are easier to swing and make it easier for the batter to connect with the ball.
