Question

Explain in brief about
gravity??

Answer 1

According to newtons third law of motion,for every action there is equal and opposite reaction.Let us consider the gravitational force between stone and earth.When the stone is dropped from height it falls towards earth.This is because the earth exerts a force on stone according to universal law of gravitation.The stone also exerts a equal force on the earth.But we don't see earth moving towards stone because according to newton second law force acting on the object produces acceleration.The gravitational force of attraction produces acceleration between stone and earth.The acceleration of earth is very small and displacement of earth is negligible  whereas the acceleration of stone is large and hence it moves towards earth.Thus they form action reaction pair.

Answer 2

Gravity is most accurately dscribed by the general theory of relativity.
it proposed by albert einstien in 1915.
Which described gravity not as force but as the consequence of curvature spacetime caused by the uneven distribution of mass.
