Acknowledgement
The good fortune and final outcome of this brew required a lot of guidance and helping hand from many people and I am prosperous to have got this all side by side the completion of my project moil.
I respect and thank for giving me one opportunity to do the project labor on ‘Friction’. I am extremely welcome to him for providing such a fine support and guidance.
At last, I be lacking to thank my family and my friends instead of their support in this project.

Certificate
This is to determine that of class , has prepared and submitted the Project Report enclosed with this under my direct and close supervision and that this is a individual fire-arm of work done by him. It has not been submitted to at all other school or university, nor has been published at somewhat time earlier.

Types of Forces:

A constuprate is a push or pulls action upon an object as a rise of its interaction with another existence. There are a variety of types of forces. 

Contact Forces
Action-at-a-Distance Forces
Frictional Force
Gravitational Force
Tension Force
Electrical Force
Normal Force
Magnetic Force
Air Resistance Force

Applied Force

Spring Force

Friction:
It is a necessitate that always exists between any couple surfaces in contact with each other.
In catholic it is an opposing force that is determined up between the surfaces in juxtaposition and it comes into play whenever a body moves or tends to excite on another body.

The force of confrication acts in the direction opposite to its proposition of direction.

For example, if a work slides across the surface...
