We were tasked with designing an experiment based on measuring the efficiency of a bouncing ball. And so for this we would have to calculate the rebound height experimentally to obtain a quantity useable for measuring efficiency.
However, when trying to measure the height it reaches with the naked eye we encounter errors on reaction time and measurement against a piece of straight meausing tape.
Should this be first attended in a simulation under similar conditions or is there a way to measure the height the ball rebounds to with an accurate enough measurement in the physical world
One more thing how do we make sure that no force is added from the person when we drop the ball from a selected height. We did think of putting it on a piece of paper and pulling it away so it would fall untouched by us but that only created downspin and hence an incorrect measurement
Thanks for your help
