Non-Contact Forces

When you jump, you always return back to the surface

There something that is holding your feet when you try to jump

Also when you throw a ball high up in the air

It reaches the highest point and then it invariably return back to its thrower on the ground

This is due to the gravitational force

This force is non-contact force

Non-Contact Forces

Basically force is an interaction that causes an affected object to be pushed or pulled in a certain direction

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

When compared to the types of contact forces, there are very few non-contact forces

Types of Non-Contact Forces

Gravitational Force: Gravitational force is responsible for bringing the items we toss into the air back to earth

The gravitation is a force of attraction that exists between all bodies that have mass

The gravitational force of the sun keeps the Earth and all the other planets of the solar system is a fixed orbit

Gravitational force does not need to be in contact to exert its downward force

Electrostatic Force: The electrostatic force is very similar to gravitational force, the difference is electrostatic force acts between two charged bodies

If you rub a comb on your clothes and then hold it near tiny pieces of paper you will see the bits of paper standing on their end attracted to the comb

The opposite charges attract each other and like charges repel

Magnetic force: Iron pins are attracted in the presence of a magnet bar without any physical contact

This is the result of magnetic force

In all these forces, one common thing is that there is no contact between the bodies still the force is experienced

These are how non contact forces work

Revision

Non-contact forces come into play when objects do not have physical contact between them

Types of Non-Contact Forces are: Gravitational Force Electrostatic Force Magnetic Force
