Give one example for contact force and non contact force?

contact force----------------- hammering a nail
non contact force---------------- magnetic force

contact force---kicking ball, pushing an object
non contact force--gravitational and magnetic forces

contact = muscular force                                   non- contact = electrostatic

A non-contact force is a force which acts on anobject without coming physically in contact with it. The most familiar example of a non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.
 

contact forces------kicking a ball
non contact forces------magnetic attraction

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar example of a non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.

Contract -----------Muscalar Force
Non contract----Gravitional force

Muscular force is the example of contact force.
Magnetic force is the example of non contact force.

One eg. of contact force is muscular force and one of non contact force is magnetic force

Contact force-string
