Question

Give any two examples of contact and noncontact force.

Answer 1

CONTACT FORCES:1. pushing a car up a hill
                                  2. kicking a ball
NON-CONTACT FORCES:1. gravitational force
                                           2. nuclear force

Answer 2

The most familiar example of a non-contact force is weight. In contrast a contact force is a force applied to a body by another body that is in contact with it. However it is to be noted that the origin of all contact forces (such as friction) can be traced to non-contact forces......

The non-contact force acts on the physically separated objects; for example, gravitational force or the force between the sun and stars, electric force, magnetic force. The contact force acts on the interacting objects which are physically connected with each other; for example, normal force, friction, applied force, air resistance, tension etc.
