Differences between gravity and acceleration due to gravity (g).

Gravity	Acceleration due to gravity
Gravity is a force.	Acceleration due to gravity is acceleration.
Its SI unit is Newton.	Its SI unit is m/s2.
Gravity is a force of attraction between the earth and a body.	The acceleration attained by a freely falling body under the influence of gravity is called acceleration due to gravity.
Gravity is a cause.	Acceleration due to gravity is an effect.

As per Newton’s universal law of gravitation

Gravity at a point R meter away from the centre of the earth is given by:-

F = G. ME. mb / R2 Newton.

Where

Acceleration due to gravity (g) at a point R meter away from the centre of the earth is given by:-

g = G. M E / R 2 m/s 2
