Any Ideas For A Soccer Science Fair Project?

This one is a hard one. The measuring is hard and the power of your kick won't be the always the same. But if you find an answer for the measuring please reply

You can try  doing a project like does the shape of a soccer ball affect its speed or does the shape and weight of the ball affect its bounce or speed
