Question

1. What is the difference between a contact force and a noncontact force? Give examples.​

Answer 1

Explanation:

• A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar 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 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.
