Question

define of Gravitational force

Answer 1

HEY!!

Gravity is not a property of the earth alone. In fact, every object in the universe, whether small or large, exerts a force on every object. This force is known as gravitational force.

Answer 2

$\sf{\underline{\underline{Gravitational\:force-}}}$

All bodies on the Earth experience this force due to the Earth. Gravity governs the motion of moons around a planet, motion of planets around the sun. It plays a main role in formation and evolution of stars,

galaxies and galactic clusters. Newton's law of gravitation gives the magnitude of force exerted by a particle of mass m, on another particle of mass m, at a distance r from it as

$\boxed{\sf{\red{F = G \dfrac{m_{1} m_{2}}{r^2}}}}$

where G is universal gravitational constant. G = 6.67 x 10^(-11) Nm²/kg².This force lies along the line joining the two particles.
