I'm working on a computer program which involves some physics. I want to know if the mass of a perfectly rigid ball will affect how high it bounces off the ground. I'm in high school and I haven't studied physics just yet.

If the mass does affect bounce, please provide the governing equations. Thanks.

  • $\begingroup$ In my case, the ground. I've added it to my question. $\endgroup$

  • $\begingroup$ Is the ground also perfectly rigid? $\endgroup$

  • $\begingroup$ Yes, the ground is perfectly rigid. $\endgroup$

  • $\begingroup$ A frictionless, perfectly rigid ball should conserve the energy when bouncing on a perfectly rigid ground. Therefore its mass doesn't play any role and the height of its bounces depends only on initial position and velocity.all. $\endgroup$
