उत्तर
| The force of friction | Gravitational force |
| The force which acts opposite to the direction of motion of a body is known as the force of friction. | It is the force that is exerted by the earth on every object, which is near or on its surface. |
| It is a contact type of force. | It is a non-contact type of force. |
| For example, a ball rolling on the ground stops after some time because of frictional force acting between the ground and the ball. | For example, an apple falling from a tree branch towards the ground is due to gravitational force. |
