AbstractDid you know that throwing, kicking, and punting a football all involve the science of projectile motion? A star NFL® quarterback, kicker, and punter each need to have a very good understanding of how a football moves through the air in order to help them win games. In this science project, you will set up a rubber band-powered catapult to represent a field goal kicker, and study how changing the distance from the goalposts affects how hard it is to accurately kick a field goal.ObjectiveUse a rubber band catapult kit and a toy football to kick field goals and see how your success rate varies with distance. IntroductionHave you ever seen a National Football League (NFL®) game with an exciting, game-winning touchdown pass or field goal? Believe it or not, there is actually a good deal of physics behind those passes and kicks. The science of how an object (like a football) moves through the air when it is launched, kicked, or thrown is called projectile motion. Projectile motion tells you how forces like gravity and air resistance affect the path an object follows when it moves through the air, also called its trajectory.

To land in a receiver's hands or pass through the field goalposts, the football needs to follow a specific trajectory, as shown in Figure 1. Figure 1.A football needs to follow a certain trajectory for a player to make a successful field goal. To score points, the player must send the ball between the goalposts. If the ball does not go far enough (the kick is 'short'), or if the ball goes to the left or right of the goalposts instead of between them (the kick is 'wide'), then the field goal does not count.However, not every pass or kick is perfect. It can be hard to concentrate when you have a 300 pound linebacker running at you full speed!

There are many factors that can affect whether or not a field goal is good, including how the ball is held in place for the kicker, weather conditions like wind and rain, and how far the ball is from the goalposts. If you watch a lot of football, you have probably noticed some of these things. In this sports science project, you will test just one of these variables: distance. You will set up a rubber band-powered catapult to act like a kicker's leg, and use it to kick field goals with a small toy football. You will adjust the distance between the kicker and goalposts, and see how accurately you can kick field goals at each distance. Set up your catapult. Get the catapult, metal pin, and a single rubber band from your catapult kit, as shown in the top left picture of Figure 3.

Push the pin through the hole in the base of the catapult (the black part) to lock the circular metal disc in place, so the 45 on the disc is showing just below the black bar (see Figure 3, top right). Notice that the metal disc has multiple holes, so you have to push the pin through the correct hole to line up the 45. Note: This pin sets the 'follow-through angle', or how far the catapult arm will keep moving after it makes contact with the ball. For this experiment, you will keep the follow-through angle constant. If you want to find out what happens when you change this angle, see the tab.

There is a large hole in the top of the metal disc. Push a rubber band through this hole and hook it on both sides of the pin that sticks through the catapult's launch arm (see Figure 3, bottom left). When you are done, the assembled catapult should look like the bottom right image in Figure 3.

Figure 3.The catapult, rubber band, and pin (top left). Use the pin to lock the metal disc in place relative to the base of the catapult (top right). Loop a rubber band through the large hole in the metal disc, and hook it on both sides of the pin sticking through the launch arm (bottom left).

The assembled catapult (bottom right). Clamp your catapult to a piece of furniture. Use a clamp (either the spring clamp that came with the catapult kit, or a C-clamp; a C-clamp will probably work better) to clamp your catapult hanging upside-down from a piece of furniture, like a table or a desk, as shown in Figure 4. Remember that you may need to move around some furniture in your house to have enough room for the experiment. Make sure you have at least 4 or 5 meters (m) of open space in front of the catapult. Note: In NFL games, distances are measured in English units: yards, feet, and inches. However, scientists always use metric units, so for your science project, you should always measure distances in meters.

Important: If you do not watch to scratch the furniture, use paper towels or a small dish towel as padding between the furniture and the clamp. Figure 5.This goalpost is made from cardboard, duct tape, and a small trash can. Set up your goalpost in front of your catapult.

Set up your goalpost as far as possible from the catapult. When you do the experiment, you will start out at the farthest distance and gradually move the catapult closer.

Ideally, you should set your goalpost up 5 m from the catapult. If you go much farther than that, you may go out of the catapult's range. If you do not have that much space available, you may need to start with the catapult closer. Set up your kicking tee.

Use something like a medicine cup or a small bottle cap as a kicking tee (see Figure 6). Using a stack of cardboard boxes or books, as necessary, set up your kicking tee so the ball is at just the right height to be 'kicked' by the end of your catapult arm when it swings (see Figure 7). The exact height of boxes/books that you need will depend on the height of the furniture you clamped your catapult to. Figure 7.This picture shows a textbook and two cardboard boxes used to adjust the kicking tee to the appropriate height for the catapult.Kick Some Field Goals!.

Make a data table like Table 1. Note: Depending on the amount of space you have to work with, you may have to adjust the distances in the first column. Try to make sure you test at least four different distances. For example, if you only have 4 m of total space, you could test distances of 1, 2, 3, and 4 m. If you have more space available, you could test 1, 2, 3, 4, 5, and 6 m.

Distance (m)Field Goals MadeField Goal AttemptsField Goal Percentage12345Table 1. A data table to keep track of your field goal kicking. Remember that in NFL games, distances are measured in yards, but for your science project, you should use metric units and measure in meters (m). Double check to make sure your goalpost is set up at the farthest distance from your data table. For example, if you are using an exact replica of Table 1, you should put your goalpost 5 m away from your catapult. Take some practice kicks to get used to using the catapult setup.

Use one hand to pull the arm of the catapult back, while you carefully place the football in the kicking tee with your other hand. Move your free hand out of the way once you have placed the ball, so you do not hit your fingers!. Let go of the catapult arm; it will immediately swing forward and hit the football. Did it go through the goalposts?

If so, you scored a field goal!. If the ball did not go through the goalposts, you may need to make some adjustments to your catapult setup. This part will take some trial and error, depending on how far off your first kick was. There are several different things you can try to help aim your kicks:. If the ball did not go far enough (the kick was too weak), you can add more rubber bands to your catapult. Your catapult kit came with three rubber bands.

Try adding one or two more rubber bands the same way you attached the first one. This will make each 'kick' stronger. You can also adjust how far back you pull the catapult arm before releasing it. The farther back you pull the arm, the more it stretches the rubber band, so the harder it will kick the ball. If the ball is going too high or too low, try adjusting the height or the forward-backward position of your kicking tee slightly. This will change where, during the swing, the catapult comes into contact with the ball, which will affect how high or low it is kicked.

If you are missing field goals wide left or wide right, try adjusting the left/right position of the tee slightly. This can affect whether the ball goes straight or hooks to the side. Once you have found a good setup to kick field goals, you need to record the settings you are using to make sure you can do repeated trials. Pay attention to how far back you pull the catapult arm.

You can do this by reading the angle markings printed on the metal disc on the catapult. For all future trials, make sure you pull the catapult arm back to the same spot. This will ensure the ball always goes far enough.

Pay very close attention to exactly where you place the kicking tee, as this can have a big impact on where the ball goes. Physicists have a big goal in mind—to understand the nature of the entire universe and everything in it! To reach that goal, they observe and measure natural events seen on Earth and in the universe, and then develop theories, using mathematics, to explain why those phenomena occur. Physicists take on the challenge of explaining events that happen on the grandest scale imaginable to those that happen at the level of the smallest atomic particles. Their theories are then applied to human-scale projects to bring people new technologies, like computers, lasers, and fusion energy.

Mechanical engineers are part of your everyday life, designing the spoon you used to eat your breakfast, your breakfast's packaging, the flip-top cap on your toothpaste tube, the zipper on your jacket, the car, bike, or bus you took to school, the chair you sat in, the door handle you grasped and the hinges it opened on, and the ballpoint pen you used to take your test. Virtually every object that you see around you has passed through the hands of a mechanical engineer. Consequently, their skills are in demand to design millions of different products in almost every type of industry. Variations. If you watch football games or play football yourself, you have probably noticed that real kickers follow through with their leg when they kick the ball.

You can use the pin that locks the metal disc to the catapult's base to change the 'follow-through' angle of the catapult arm. The pin determines where the catapult arm stops, which controls how far it will keep moving after it initially makes contact with the ball.

Try a new experiment to measure how changing this angle affects your field goal percentage. Use a tape measure to measure how far the football goes when you:. pull the catapult arm back to different angles. change the follow-through angle (as described in the previous variation). use a different number of rubber bands. NFL kickers wear special shoes designed just for kicking.

In this science project, you just used the cup at the end of the catapult arm as a 'shoe.' Explore how the size, shape, and material of the 'shoe' affects the ball's trajectory. For example, what happens if you tape a flat piece of cardboard over the cup instead?. What happens if you change the tee position? Create a science project to measure how the tee position affects the trajectory of the ball.

Is there an optimal tee position to get the best field goal percentage?

A: There are three ways you can adjust the left-right aim of your catapult. Which one you use will depend on your setup:. You can rotate the entire catapult. This may be difficult to do if you have it clamped to a large piece of furniture like a table. You may have to ask an adult to help you rotate the entire table slightly. You can just move your goalposts to the left or to the right, as necessary.

This may be easier than rotating the catapult itself, since the goalposts are smaller and lighter than a large piece of furniture. You can adjust the left-right position of the kicking tee slightly. Ideally, if you 'kick' the ball dead-center, it will go straight. If you have already adjusted the aim of the catapult and the position of your goalposts, make sure that the catapult arm is impacting the center of the ball, and not hitting the sides. A: Two things can affect how high the ball is kicked: the height of the kicking tee and the forward-backward position of the kicking tee.

Make sure the kicking tee is positioned slightly forward, so the catapult arm impacts it while it is on the 'upswing'. This will ensure that the catapult arm kicks the ball up into the air, and not down towards the ground. You can also raise the height of the kicking tee slightly, for example by stacking thin paperback books or pieces of cardboard underneath it one at a time.

A: It is okay if you cannot make 100% of your field goals, even if you very carefully set up the aim of your catapult to begin with. There will always be some natural variability in the trajectory of the ball, no matter how tightly you try to control it—that is the point of this science project!
