Answer 2

Answer:

1. Contact force: the forces which are applied on bodies by making a physical contact with them, are called Contact force example: the force of friction : when a body slides (or rolls) over a rough surface a force starts acting on a body along the surface in contact. this is called frictional force or the force of friction.
2. Non contact force : the forces experienced by bodies even with out being physically touched are called non contact force example:Magnetic forces: two unlike poles repel while two unlike magnetic poles attract each other the forces between the magnetic poles is called the magnetic force.
