Experiment:

Question:

What can Ms. Santa read from the recording of the bouncing ball?

A) The ball height decreases, the proportional energy loss in % remains about the same.

B) The ball height decreases, the proportional energy loss in % increases.

C) The ball height decreases, the proportional energy loss in % decreases.

D) The ball height remains the same, the proportional energy loss in % increases.

Advice of the day:

Since we cannot measure so precisely, changes of a few percent (+-10%) should be considered constant. An increase or decrease should be at least +-30%.
