Question

What is contact and non - contact force .​

Answer 1

$\bold{Contact \:force: }$

•The forces which act on bodies when they are in physical contact are called contact forces.

•Types of contact forces: frictional force, normal reaction force, tension force as applied through string etc.

$\bold{Non\: contact- force: }$

•The force experience by bodies even without physical touched are called non- contact force or force at a distance.

•Types of non - contact force are : Magnetic force, electrostatic force and gravitational force.

Answer 2

$\mathfrak{\large{Contact\: Force}}$

• Force that act only when there is physical contact between two interacting objects are known as contact force.
• Example :- Muscular Force and frictional Force.

$\mathfrak{\large{Non-Contact\: Force}}$

• Force is being applied Without touching the body. This is called action at a distance force. It is also called Non - Contact Force.
• Example:- Gravitational Force, Magnetic Force and electrostatics force.
