Question

Gravitational force defination,s.I.Unit,dimentional formula

Answer 1

Definition of the Gravitational Force ⇒ The Force acting on the heavenly bodies like earth, which attracts the particles towards itself is called as the Gravitational Force.

F = Gm₁m₂/r²

where, F is the Gravitational Force,

m₁ and m₂ are the masses of the object, and G is the Universal constant of the Gravitation.

The S.I. Unit of the Gravitational Force is Newton.

Dimensional Formula of Gravitational Force = MLT⁻²

Hope it helps.

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
