Solution

Contact Force Non-Contact Force

Contact force is the force in which a direct contact between two bodies is required. Non-contact force is the force in which two bodies interact without any direct contact.

For example: When you stop pedalling a bicycle, it slows down and stops after some time. This is because of the frictional force or contact force. For example: When a ball is thrown upwards, it ultimately falls down because of the gravitational force of the Earth. In this case, the gravity of the Earth forces the ball to fall down without any direct contact. So, it is a non-contact force.
