TYPES OF FRICTION;;;;;;;;;
Different types of motion of the object gives rise to different types of friction.Generally there are 4 types of friction they are Static friction, Sliding friction, Rolling friction, Fluid friction.Lets discuss about each type of friction in detail.
=== ''STATIC FRICTION'' ===
Static friction exists between a stationary object and the surface on which it is resting.It prevents an object from moving against the surface.
=== ''SLIDING FRICTION'' ===
Sliding friction occurs between objects as they slide against each other.
When sliding friction is acting there must be another force existing to keep the body moving.
=== ''ROLLING FRICTION'' ===
Rolling friction is the resistive force that slows down the motion of a rolling ball or wheel. It is also called rolling resistance.
When a force or torque is applied to a stationary wheel, there is a small static rolling friction force holding back the rolling motion. However, resistance from static sliding friction is what really causes the wheel to start rolling.
Rolling friction hinders the motion of an object rolling on a surface, that means it slows down the motion of an object rolling on a surface.
=== ''FLUID FRICTION'' ===
Here on Earth we tend to take air resistance (aka.“drag”) for granted. We just assume that when we throw a ball, launch an aircraft, deorbit a spacecraft, or fire a bullet from a gun, that the act of it traveling through our atmosphere will naturally slow it down. But what is the reason for this? Just how is air able to slow an object down, whether it is in free-fall or in flight?
air friction is experienced by the objects moving through the open air. air friction acts between the object and the air through which it is moving. It is also called drag. This force depends upon the object's shape, material, speed with which it is moving and the viscosity of the fluid. Viscosity is the measure of the resistance of the air to flow and it differs from one density another.

There are 2 kinds of friction ;
Static, it comes to play when an object is at rest
Kinetic, it comes into play during the movement of any an object.
It is of 2 types;
1,Sliding
2,Rolling
