# Explain briefly about Newton's law of gravitation

Newton's law of Gravitation-

• According to Newton's law of gravitation, the gravitational force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Due to gravitational force, Each particle in this universe attracts every other particle.

The direction of this force is along the line joining the particles.

Let two particles of masses and separated by a distance r exert  a Force F on each other

And Magnitude of F is given as Or, Where Force Gravitational constant Masses Distance between masses

•  The vector form of formula According to Newton's law of gravitation Or Where Position vector

Here negative sign indicates that the direction of is opposite to that of And So, Means Gravitational force between two bodies form an action and reaction pair.

i.e. the forces are equal in magnitude but opposite in direction.

This is in accordance with Newton's third law of motion
