What is garavitation?

Answer 1

We have learnt that a force is needed to change speed or direction of motion of an object.We always observe that an object dropped from a height falls toward the earth.We know that all planets go around the sun.The moon go around the earth.In all these cases,there must be some force acting on objects,the planets on the moon.Isaac newton could grasp that the same force is responsible for all these.This force is called gravitational force.

Answer 2

I believe you meant to ask about gravity. Gravity is the force that attracts objects with mass towards each other. It is responsible for keeping planets in their orbits around stars and for giving weight to objects on Earth.
