Friction
When the surface Area contract and one Earth is moving on the surface tension of motion force produced.

Static Friction
In a static friction every. The surface of earth surface is not changing every point of earth surface lock this friction oppose the motion of object.

Kinetic Friction
In kinetic friction every particle of the moving body changes its position description supports and stopping the moving body.

Law Of Friction
According to this friction to the law friction the force of friction between two bodies is directly proportional to the normal M is the coefficient of friction and it is the ratio between fictional force and the normal reaction.

Fluid Friction
The substance is a which can flow are called Phillip substances the friction and floods is called viscosity it is edited by of ETA was the scientist succeeded in explaining and calculating the friction and fluids.

Inclide Plane
Hhorizontal surface when makes angle theta with X axis is called as I include plane.
It is a simple machine used for doing work easier and save the energy the responsible for for the motion of object is the WX and normal reaction are cancelling to each other because of same magnitude and opposite in direction unbalanced force can be determined according to the second law of motion this acceleration produced in the body when frictional force is zero an negligible.
