Question

what is the difference between contact force and non-contact forces? give some examples of both forces.​

Answer 1

Answer:

Forces that do not need physical contact with the object on which they are acting are called Non-contact forces. These forces can act on the object without physical contact . e.g are gravitational force, electrostatic force, magnetic force.

Forces that act on objects by direct or indirect physical contact are called contact forces. These forces can act on object only when it is in contact with it either directly or indirectly. Applied forces and friction are examples of contact forces.

Answer 2

Explanation:

Contact Force

The force which acts only when an objects are in physical contact with each other.

Forces that act only when there is physical contact between two interacting objects are known as contact force.

Examples: Muscular Force and frictional Force

Non - Contact Force

The force of interaction which acts on an object without it's having any direct physical contact with another body.

Example: Gravitational Force, Magnetic Force and electrostatics Force.
