(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

This question is related to an in-class experiment. The lab involves bouncing a ball and using a motion sensor which creates a graph representing the motion.

The question is: Is the principle of conservation of momentum violated in this collision (the ball colliding with the ground)?

2. Relevant equations

m_{1}v_{1i}+ m_{2}v_{2i}= m_{1}v_{1i}+ m_{2}v_{2i}

3. The attempt at a solution

I don't think the collision violates the conservation of linear momentum law because the law applies to closed systems, and this system (when the ball collides with the earth) is not closed.

However I'm not sure if my theory on this is correct ...

Thanks in advance for your help :)
