Q. Explain what is free fall acceleration?
Answer:-
On earth free drop acceleration is 9.81 meters per second per second or 32.2 feet per second per second not including air resistance around these parts free fall acceleration is the acceleration because of earth gravity on a body that isn't acted on by an outside force like air resistance or a bungee tether.
