Why is gravity an acceleration?

On the surface of the Earth gravity is equivalent to an acceleration of approximately . That is an object in free fall in Earth's gravity will increase its velocity (towards the centre of the Earth) by every second (ignoring air resistance etc). From rest it will drop slowly at first, then get faster and faster. In this manner, is gravity an acceleration? In physics, gravitational acceleration is the free fall acceleration of an object in vacuum — without any drag. This is the steady gain in speed caused exclusively by the force of gravitational attraction. Additionally, what is acceleration due to gravity G? In the first equation above, g is referred to as the acceleration of gravity . Its value is 9.8 m/s 2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s 2 . When discussing the acceleration of gravity , it was mentioned that the value of g is dependent upon location. Similarly, it is asked, why does gravi...
