Science Fair Project Idea
 For example, think of hitting a baseball, heading a soccer ball into the net, or hitting a tennis ball with a racquet. Where the ball goes depends on...what? You can set up a simple model to start your investigation. You'll need a marble, a flat piece of wood, a flat piece of cardboard, a pencil, a ruler, a protractor, and a level surface. Lay down the cardboard down on a level surface and set up the flat piece of wood at one edge. The wood will act like a wall, and you're going to roll… Read more

Science Fair Project Idea
 For this project, you'll use a baseball as a pendulum weight, studying the motion of the ball with and without spin. Wrap a rubber band around the ball, and tie a string to the rubber band. Fasten the string so that the ball hangs down and can swing freely. Mark a regular grid on cardboard, and place it directly beneath the ball to measure the motion. You can also time the oscillations with a stopwatch. Lift the ball along one of the grid axes, and let it go. Observe the motion and record… Read more

 In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

 Time Required Average (6-10 days) Prerequisites To do this project, you should understand what a coordinate system is and know how to make a simple scatter plot. Material Availability This science project requires a kit available from the Science Buddies . See the Materials and Equipment list for details. Estimated project time includes shipping. Cost Average (\$40 - \$80) Safety Never launch projectiles at people or animals. Be careful not to get your fingers caught in the moving parts of the catapult.
Science Fair Project Idea
 Imagine a symmetrical grid of nine points superimposed over the ball. Kicking the ball squarely on the center point imparts no spin, but kicking on any of the other points will impart spin on the ball. How will the resulting spin affect the trajectory of the ball for each of the 8 outer grid points? Kicking the ball with a sliding motion of the foot is another way to impart spin. Once you've made your predictions, you can set up to test them with a soccer ball, video camera and a tape… Read more

 Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back! What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing. Read more

 Tennis racquets, baseball bats and golf clubs all vibrate when they hit the ball. You can often feel it in your hands, particularly if you "mis-hit" the ball. You can find the point(s) on your racquet, bat or club—called the "sweet spot"—that minimize unwanted vibrations. Low-tech method: hang the racquet or bat straight up and down with a string from its handle. Lightly hold the handle with your thumb and forefinger and have a helper sharply tap the bat, strings or club face… Read more

 How high can you throw different types of balls, like a golf ball, a basketball, and a football? Would one of them go higher than the others? Do factors like mass, shape, and volume influence the final height? You can measure the approximate maximum height a thrown ball reaches by measuring the time it spends in the air. To do this project, you'll need at least one ball and a helper with a stopwatch. Your helper should start timing just as you release the ball, and stop right when the ball… Read more

 If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more

 Many sports skills require quick reaction times: think of hitting a 95-mph fastball, returning a 100-mph tennis serve, or blocking a slapshot at the net in hockey. (The Experimental Procedure section below has one way to measure reaction time.) Is your right hand faster than your left? Can you improve your reaction time with practice? Do both hands improve if you only practice with one hand? Try relating your reaction time to real situations in your favorite sport. For example, calculate… Read more

 You are right next to the basket and someone passes you the ball. Will you go for a direct shot or will you use the backboard and take a bank shot at the basket? Would different positions on the court give you a higher chance of making a shot using the backboard than others, even when keeping the distance from the hoop the same? In this science project, you will build a scale model and test different positions on the court to determine if one results in a better chance of making a bank shot… Read more
