What is Contact Force?
A contact force is any force that requires contact to occur. If two surfaces are not in contact, they can’t exert a normal force on each other. Some types of contact forces are listed below.

Applied Force:
It is the direct force applied to a body by another body.
Example: When you push a bottle across a table, it is an example of applied force.

Frictional Force:
Friction is the force experienced by an object when it moves or tries to move on a surface. It is a resisting force.
Example: Resistance experienced by a kid while coming down a slide or by a ball rolling on concrete.

Air Resistance Force:
Air resistance is a type of frictional force experienced by objects moving through air. Like normal friction, air resistance is also resistive by nature. The power of this force depends on the speed of the object as well as its surface area.
Example: A skydiver using a parachute experiences air resistance which slows him down and allows him to land safely.

Tension Force:
Tension is the force experienced by a fully stretched object such as a string. Tension force acts along the wire and exerts equal pressure at each end.

Example: The tension in the strings of a guitar decides the nature of its vibration and as a result, the nature of the sound it will make.

Spring Force:
It is the force exerted by a spring when it is compressed or stretched.
Example: If you stretch a spring and then leave it, it will return to its original position as a result of spring force.
