Free fall acceleration
What do you mean by the term free fall acceleration? State its significance in brief?
Expert
On earth, the free fall acceleration is 9.81 meters per second per second or 32.2 feet per second per second, not comprising the air resistance.
Around such parts, free fall acceleration is the acceleration due to the earth gravity on a body which is not acted on by an exterior force (similar to air resistance or a bungee tether).
