Question

How to expand the equation of acceleration due to gravity (g) from the equation of law of gravitation?


plz fast​

Answer 1

Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
