Homework Statement
I need to know whether a ping pong ball bounces the same fraction of the previous height or does the fraction change? For ex. if I drop the ball from 1m and it bounces back to 0.7m, it decreased by 30%, will it always decrease by 30%, or will the percentage change?
Homework Equations
The Attempt at a Solution
I have done an experiment and it looks like the percentage of the height that it decreases by will increase, in my case first it was decreasing by ~25%, then 20% and by the end it was about 15%, there was a big uncertainty in my results, but it looked like it had a tendency to decrease. Can I explain/prove that somehow? Or is it just the uncertainty playing tricks on me?
