What do you mean by acceleration due to gravity?

Explanation

When an object is dropped from some height, its velocity increases at a constant rate. In other words, when an object is dropped from some height, a uniform acceleration is produced in it by the gravitational pull of the earth and this acceleration does not depend on the mass of the falling object. The uniform acceleration produced in a freely falling object due to the gravitational force of the earth is known as acceleration due to gravity (g). The value of acceleration due to gravity (g) changes slightly from place to place but for most of the purposes it is taken to be `9.8 m//s^2`
