Universal Law of Gravitation
Universal Law of Gravitation
The Universal Law of Gravitation:
The law was formulated by Newton. The gravitational force of attraction between any two particles in the universe is directly proportional to the product of the masses of the particles and is inversely proportional to the square of the distance between the particles. The direction of the force is along the line joining the two particles. Let A and B be two particles of masses and
respectively. Let the distance AB = r. By the law of gravitation, the particle A attracts the particle B with a force F, such that
F ∝ (for a given separation between the particles)
Here “G” is a constant known as the universal constant of gravitation. The value of G was experimentally measured in the laboratory by Cavendish, long after Newton’s death. This value is

8thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
