How to find the acceleration due to gravity when a bouncy ball is being dropped?
If the ball is dropped (not thrown), then the acceleration from gravity on Earth will have the same effect it always does, and the ball will accelerate at 9.81m/s^2. If the problem is asking for just the acceleration, then that’s it, no calculations required. If it’s asking for something else like its velocity when it hits the ground or something then use 9.81m/s^2 as the acceleration and one of your basic formulas for calculating the rest of the info.
