Question

. Explain contact and non-contact forces. Give two examples for each.

Answer 1

Answer:

Contact Forces : The forces which are applied on bodies by making a physical contact with them, are called contact forces. e.g. Frictional force, Muscular force .

Non-contact Forces : The force experienced by the bodies even without being physically touched, are called non-contact forces. e.g. Gravitational force, Magnetic force.

Answer 2

Answer:

HEY THERE,

Contact force is a force that is applied by objects in contact with each other. Contact force acts on a point of direct contact between the two objects. This force can either be continuous as a continuous force or can be momentary in the form of an impulse. Contact force is governed by Newton’s Laws. Contact force is responsible for most of the interactions we experience in the daily life. Pushing a car up the hill, writing your name with a pen or picking up a textbook from the table are all examples of contact force and they are also examples of continuous force.

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. When compared to the types of contact forces, there are very few non-contact forces.Ex:Gravitational force
