![]() ![]() If the masses of object are large,gravitational force between them is very large. The gravitational force of earth is responsible for holding the atmosphere above earth,for rain falling on earth,for flow of water in rivers,keeps us firmly on ground,ball thrown upwards also falls back to earth due to gravity.Įvery object in this universe attract every other object with a certain force.The force with which two objects attract each other is called gravitational force. The force with which the earth pulls the objects towards it is called gravitational Force of Earth. ![]() This force of attraction exerted by earth is called gravity. Issac newton was sitting in his garden under a tree.When an apple from tree fell on him.He said that an apple fall down from tree towards earth because the earth exerts a force of attraction on the apple in the downward direction. If we drop a stone from height,the stone falls down towards the earth.Because the earth exert a force of attraction on the stone and pull it down. Question 7 What is centripetal force.Explain?Ī force is necessary to produce motion in a body,to change the speed or direction of motion of an object. Question 6 What happen to the gravitational force between object when the distance between them is doubled and halved? ![]()
