The acceleration observed in any body due to gravity is called Acceleration due to gravity.
The force due to gravity is given by,
Where m = mass of the body and
g = gravity.
The Universal Law of gravitation gives,
Where G is a constant equal to 6.67 $\times$ 10-11
= mass of the body 1, M
= mass of body 2, r
= radius between the two bodies.
Equating both the force formula we get
Hence Acceleration due to gravity formula is given as
The above formula can also be called Gravitational Acceleration Formula. It is used to find the acceleration due to gravity any where in space. On earth the acceleration due to gravity is 9.8 m/s2.
