When a ball is kicked straight on with the instep of your foot, it travels straight. Investigate the relationship between spin and trajectory of the soccer ball. State in your conclusion whether the ball you chose in your hypothesis matched up with the results of the experiment. Compare the distances on a line graph and determine whether or not the panels affect the ball’s velocity. Explain in your project your experiment and how you executed it. Measure how far the ball travels and take the average distance for each ball. Have your friend kick each ball ten times using the same force. Each soccer ball will have varied amounts of panels on the exterior, usually anywhere between 12 and 32. Bring a friend with you to the soccer field along with four soccer balls. Even though all of the balls look round, there could be slight differences in them due to the amount of panels and stitches it took to make it. The way the ball is stretched and stitched together along with the material makeup of the ball can affect the shape of the ball and the way it compresses the air inside. Write a hypothesis stating which ball you think will travel the farthest. Write a conclusion evaluating your hypothesis in regards to the conclusion of your experiment.Įxperiment with how the stitching of a soccer ball can affect the distance it travels. Compare the distances of the ball to determine the optimum air pressure for performance. Write an explanation of your experience including how far you pulled the ball back in the slingshot. Increase the pressure each time by two pounds until you get to twelve. Repeat the test again by adding two more pounds of air pressure to the ball. Perform the experiment two more times by launching the ball from the same place. Put two pounds of pressure in the ball and launch it with the slingshot. Build a slingshot or use a water balloon launcher to test the distance of the ball. This will cause the ball to bounce harder and affect the way the ball travels after hitting a surface. When there are more air molecules inside the ball, the tension on the wall of the ball increases. The air pressure affects the ball because of the number of air molecules inside. Write a hypothesis with your opinion of what the optimum air pressure for a soccer ball is. Study the relationship between air pressure and how far a soccer ball travels. Write a conclusion comparing your hypothesis to the results of the experiment. Graph the data on a bar chart to show each type of field. Write an account of your experiment for your project. Drop the ball ten times at each field and use the average number of bounces of each field in your analysis. Count how many times the ball bounces on each type of turf. Have your friend climb on top of a ladder and drop the ball from six feet in the air. Bring a friend with you to help with your testing. When the air decompresses after impact, the potential energy will be converted to kinetic energy when the ball bounces upwards. This converts the kinetic energy to compressed potential energy. After the ball hits the turf, the ball deforms upon impact. When the ball drops, the potential energy converts to kinetic energy. You will be dropping your ball from six feet above the turf. You will need to consider the energy of your ball when forming your hypothesis. Write a hypothesis as to which turf you think the ball will be the bounciest on. Select a field that's planted with Kentucky bluegrass, one with Bermuda grass and one that has artificial turf. Find three types of turf where you can perform your experiment. A science fair project based on the effects of different types of turf on the bounciness of a soccer ball studies the physics and energy of the ball.
