Contact force occurs due to the contact between two different objects. Non-contact force occurs due to either attraction or repulsion between two objects such that there is no contact between these objects. ... The frictional force is an example of a contact force. Gravitational force is an example of a non-contact force.
Contact forces Non-contact forces
These are forces which need a physical touch on the object to act upon it. These are forces which do not need a physical contact to act on an object.
These may or may not be natural forces. These are natural forces
They can not work from a distance. They can work from a distance as well.
Its various types are applied force, normal force, tension frictional force its various types are magnetic force electrostatic force,gravitational force
