Question

define non contact force ​

Answer 1

Non-Contact Forces:

The forces experienced by bodies even without being physically touched are called the Non-Contact Forces or the Forces at a distance.

Examples of non-contact Forces:

Gravitational Forces:

The body on a force due to earth's attraction is called the force of Gravity. In the universe, all particles attract one another due to its mass.

Electrostatic Force:

Two like charges repel and 2 unlike charges attract each other, the force between these charges is called Electrostatic Force.

Magnetic Force:

Two like magnetic poles repel and 2 unlike magnetic poles attract each other, the force between these magnetic poles is called Magnetic Force.

General characters of non-contact forces:

The gravitational force is always of attractive nature, while the electrostatic and magnetic forces can be either attractive or repulsive.

The magnitude of Non-Contact forces depends on the distance of separation between them. It decreases with the increase in separation and increases with the decrease in separation.
