Goal! Can You Handle the Pressure?

CSEF · 2008 Applied Mechanics & Structures

Amanda B. Castillo · Lipman Middle School, Brisbane, San Mateo County

Overview

Objectives/Goals Show how different inflation levels affect the distance that a soccer ball will travel when it is kicked. Methods/Materials First, we made a large pendulum using 2 ten foot ladders and a sledgehammer taped onto 1# electrical metallic tubing. The ball was hit ten times for each air pressure; 3 psi, 8 psi, 14 psi. Record the distance at where the ball first hits the ground. Results Although the inflation levels were different, the distance that the soccer ball traveled stayed in the range of 25#-0# to 30#-0.# Conclusions/Discussion The ideal air pressure for a soccer ball is 6-8 psi. Higher inflation levels may make the ball travel further but it doesn#t make a big difference. I think acceleration is a bigger factor in making the ball travel further.

Summary statement

Changes in inflation levels does not adversely affect the distance a soccer ball travels when kicked.

Help received

Mr. Dettmer, advice on how to eliminate variables.; Dad helped me set up the pendulum ; Mom recorded measurements; Sister retrieved balls hit.
