Difference Between Gravitation and Gravity

Even though both the terms sound alike but there is a difference between gravitation and gravity, gravitation is the force occurring between two bodies whereas gravity is the force occurring between the earth and a body.

Difference Between Gravitation and Gravity

Gravitation is referred to the force acting between two bodies which can be represented as the \(F=(GM_{1}M_{2})/R^{2}\) which means gravitation force is proportional to the product of the masses of the object 1 and object 2 and is inversely proportional to the square of distance between them. The gravitational force between earth and any object is known as gravity.

Difference Between Gravitation and Gravity
Gravitation Gravity
It can be an attraction force or repulsive force It is always an attraction force
It is an universal force It is not an universal force
It is a weak force It is a strong force
The force is \(F=(GM_{1}M_{2})/R^{2}\) (G= gravitational constant) The force is F=mg (g=acceleration due to gravity)
The direction of gravitational force lies in the radial direction from the masses The direction of force of gravity is along the line joining the earth’s center and the center of the body. Its direction is towards the center of the earth.
Gravitation force is a vector quantity Gravity is a vector field
The force can be 0 when separation between bodies is infinity The force of gravity can be 0 at the center of the earth
It requires two masses It requires only one mass

    This is very nice app I just love it.
    And it also improve my mask in exam.
