Report on Contact Force
Contact Force:
What is contact force?
A contact force is any force that requires contact to occur. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill or kicking a ball across a room are some of the everyday examples where contact forces are at work.
Uses of Contact force?

Pushing a car up a hill or kicking a ball across a room are some of the everyday examples where contact forces are at work.
Some examples of Contact Force?
- Reaction force. An object at rest on a surface experiences reaction force.
- Tension. An object that is being stretched experiences a tension force.
- Friction. Two objects sliding past each other experience friction forces.
- Air resistance.
Who discovered the Contact Force?
It was Sir Issac Newton who discovered "Contact Force"
What is normal Contact force?
An object at rest on a surface exerts a force on the surface. The reaction force acts at right angles to the surface and is known as the normal contact force.
Types of Contact force?
- Friction Force
- Applied Force
- Normal Force
Formula of Force?
- F = ma
- F = force, m = mass and a = acceleration
What is Non - Contact force?
A non-contact force is a force applied to an object by another body that is not in direct contact with it.
Is centrifugal force acts a non contact force?
There is no centripetal force acts on the object and that means that the force cause that circular motion can be either contact or non contact force depending.
The End!
