Question

Give an expression for acceleration due to gravity.

Answer 1

1. The acceleration produced in an object that is falling freely under the influence of the gravitational force of the earth is called acceleration due to gravity.
2. It is denoted by ‘g’.
3. Its value is given by the expression $g=\frac{GM}{R^2}$, where G is the gravitational constant, M is the mass of the earth and R is the distance of the object from the centre of the earth.
