Question

What is the acceleration due to gravity and how is it different from acceleration?

Answer 1

Acceleration is the rate of change of velocity with respect to time or d²x/dt² where X= position of body.
Acceleration due to gravity is the acceleration acting on a body which is directed towards the centre of the earth due gravitational pull of Earth. The value of g varies with height or depth and varies even at the poles of the earth. In general we take g = 9.8m/s² or 10 m/s²

Answer 2

In simple language when u drop an ball from a distance above ground it falls down at a constant speed. So, its acceleration is increased by gravity thus affected by gravity. But normally if we throw a ball ,till it is going straight its acceleration is due to the force applied by the hand but when it comes down its acceleration is due to gravity.
