So, the force which is acting between the two bodies in the universe is termed as the gravitational force. In the above figure, two bodies are separated by a distance of x and the masses of the two objects are m 1 and m 2 respectively.
So, the force which acts between the two bodies is directly proportional to their masses and inversely proportional to the distance between them:. Where F is force. M 1 is the mass of the first body.
M 2 is the mass of the second body. The above equation can be further simplified as:. Where G is a universal gravitational constant whose value is 6. The G is a universal constant hence its value is the same all over the universe. The force experienced by the bodies depends on their masses as well as the distance between them. So, from the above equation, it can be concluded that the force between the bodies will be higher when the bodies are of large masses and the force will be very low in case the two bodies are separated at a very large distance with respect to each other.
Gravity is a natural phenomenon that acts between the earth surface and the object placed in the universe. The force of gravity can be defined as the force acting between the earth and an object present near it.
Gravity is directly related to earth and the object presents nearby it. As we know that the mass of the earth is extremely huge, and it is to be noted that the body of higher mass attracts the body with lower mass. Thus, it is said that the force of gravity is attractive in nature, as the earth attracts the body present near to it. Where F is the force,. M is the mass of an object,. But this acceleration due to gravity is not a universal constant and its value shows variation from place to place.
It is to be noted that the gravitational force is extremely small compared to the force of gravity. So, it can be said that two objects on the surface of the earth will not attract or repel each other easily. While earth can attract any falling body towards it easily.
This is the reason why objects fall on the ground. Now, let's understand the difference between the gravitational force and the force of gravity. The term Gravitation is said to be the force that is acting between two bodies. We know that earth is a body with extremely huge mass, and it is to be noted that the body of higher mass attracts the body having lower mass.
Thus it is said that the force of gravity is attractive in nature, as earth attracts the body present near it. G is the acceleration due to gravity and its value is 9. However, this acceleration due to gravity is not a universal constant hence its value shows variation. It is noteworthy that the gravitational force is extremely small in comparison to the force of gravity.
Hence the two objects on the surface of the earth do not attract or repel each other easily. While earth easily attracts a falling body towards it. So, from this discussion, it can be concluded that gravitation and gravity both are contextually the same in a manner that both are specified by the force acting between two bodies. Basically, it can be easily understood in a way that the force between two objects situated at a distance will be gravitational in nature. While if one of the objects is earth then it will be the force of gravity.

Skip to content The terms gravitation and gravity both are associated with the force on a body present on the surface of the earth. Key Differences Between Gravitation and Gravity The key factor of differentiation between gravitation and gravity is that gravitational force occurs between two objects. While the force of gravity occurs between the earth and an object. Gravitational force can be either attractive or repulsive in nature depending upon the direction of movement.
Class 9th Physics. Answered Views. Solutions :. Balendu Anand. Gravitation is the force of attraction acting between any two bodies of the universe. Gravity is the earth's gravitational pull on the body, lying near the surface of the earth. It requires two masses. It requires only one mass. It is a weak force. It is a strong force. G is the Universal Gravitational Constant. The value of g varies from one place to another on the Earth. Related Doubts What is the difference between artificial satellite and natural satellite?
