what is difference between gravitational force and gravitational pull?
The gravitational pull of the earth is an attraction the earth exerts on an object or the object exerts on the earth. It is proportional to the product of the masses of the earth and the object and is inversely proportional to the square of the distance between the object and the earth's center.
The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight.
