Question

The origin of all contact forces can be traced to non contact forces. justify this statement

Answer 1

A non-contact force is a force applied to an object by another body that is not in direct contact with it. The most common example of anon-contact force is gravity. A non-contact force is different from a contact force, which is a force applied to a body by another body thatis in contact with it. However it is to be noted that the origin of all contact forces can be traced to non-contact forces. Examples of non-contact forces include: Gravity, a non-contact force between two objects. The force exerted on each body by the other through weight is proportional to themass of the first body times the mass of the second body divided by the square of the distance between them. The direction of the force is from the body acted on towards the body applying the force. A human body 's weight is a non-contact force exerted by the Earth on their mass.
