and repulsion. This force,applied by a magnet,is the magnetic force.

ELECTROSTATIC FORCE A plastic pen when rubbed on hair can

attract small pieces of paper.This is due to electrostatic force.

GRAVITATIONAL FORCE Objects in the universe have an

attractive force between them.This attractive force is the gravitational force.

object,the force which opposes the relative motion of the objects is the frictional force.
