Contact force is a force that is applied by objects in contact with each other. The contact force acts on a point of direct contact between the two objects.
A non-contact force is a force applied to an object by another body that is not in direct contact with it. Non-contact forces come into play when objects do not have physical contact between them or when a force is applied without any interaction
Difference between contact and non-contact force
The difference between contact and non-contact force is tabulated below
|Contact forces||Non-contact force|
|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.|
|There is no field linked with the contact force.||There is always a field linked with non-contact force.|
|The frictional force is an example of a contact force.||Gravitational force is an example of a non-contact force.|
