theory on bouncing balls

[matha mau sen]

hi all

I'm doing an experimental investigation for a school project on bouncing basketballs. I've linked this project with kinetic and potential energy (i.e i've written how kinetic and potential play a role in the resultant rebound height) and i'm wondering if anyone knows any other theories/formula i can link my project to.

how about air resistance have you considered that?

i've decided to neglect air resistance. I'm thinking of observing the affects of heated surfaces.

Some energy is dissipated as friction in the collision and as sound. These effects are lumped together into the "coefficient of restitution." See, e.g., http://en.wikipedia.org/wiki/Coefficient_of_restitution
