Air Pressure in Footballs
What is the relationship between feedback from air pressure of a football to the
performance of a athlete?
Alex Long
Purpose
The purpose for my experiment is to work out scientifically whether the air pressure
inside a football effects the performance of a sports performer. There are several
different types and brands of footballs all with different structures and pressure
recommended for the ball. It would be interesting to find out the differences between
the different companies and whether the air pressure inside makes a big difference in
improving performance.
Hypothesis
My expected results from my experiments to answer the question is that the air pressure
which will be best for performance will be around the recommended air pressure but
slightly lower as I think that through personal experience to is easier to kick a flatter ball
than it is to kick a very hard ball. I think that the most interesting part of the experiment is
to see whether different air pressure in different brands of football make a huge amount
of difference because the balls could all basically the same with just a logo stuck on the
front of the ball.
The Experiment
Independent- what I am changing:
I am changing the air pressure between the experiments and I will be changing the
brand of football.
Dependent- what I am measuring:
The performance of a performer while kicking a ball with different air pressures inside.
Controlled- what is staying the same:
I will keep the same pump and pressure gauge so that I have the same readings. The
air temperature in the room and also the altitude I carry out the experiment. Finally I will
also keep the same athlete to under take every exercise.
Material and Apparatus
- 1x Sports Hall
- 3 different types of footballs
- 1x Pump with a pressure gauge
- 1x Athlete
- 1x Thermometer
- 1x Football goals
- 1x Stopwatch
- 25 Cones
