Question

similarity between contact and noncontact force​

Answer 1

Contact forces are forces that are exerted by contacting of two surfaces. For an example, the forces acting on each other when one object is kept on top of another are contact forces.

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.
