The forces which act on bodies when they are in physical contact. are called contact forces. For e.g. frictional force and force exerted on two bodies during a collision.
The forces experienced by bodies even without being physically touched are called the non-contact forces. For e.g. Gravitational force and Electrostatic force.
Contact force: (a) frictional force (b) normal reaction force (c) force of tension in a string
Non-contact force: (d) gravitational force (e) electric force (f) magnetic force
