ACCELERATION DUE TO GRAVITY.
In the absence of air resistance, all objects in free fall near the surface of the earth move in the direction of the earth with a uniform acceleration. This acceleration is called as acceleration because of gravity.
if acceleration vs time graph is given then how to calculate displacement
