Efficiency of a Ball - Science Practical Expiriment used ...

Balls which do not bounce high are less efficient as they have lost energy. If theoretically a ball could not lose any energy during a bounce, it would bounce back to of the height it was dropped from. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few.

Oct 22, 2007 · We don't know that's what's meant here, but it's just an example of what someone might mean. So in that case what you'd do is divide the energy the ball got by the energy you put in to get the efficiency. Calculating the ball's energy isn't hard. Perhaps the teacher gave you some sort of guidelines toward how to calculate that.

Why does a ball bounce lower? - Physics Stack Exchange

The potential energy of the ball was converted to elastic energy. You can think of it as the mass of the ball being mounted to a spring that compresses when you hit the floor - but there will be some friction (both inside the ball, and particularly between the ball and the floor) which will dissipate energy:.
