State different types of frictions

Answer»

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. 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.

Examples: static friction prevents an object like a book falling from the desk even if the desk is slightly tilted, it helps us pick up an object without slipping through our fingers.

When we want to move an object first we must overcome the static friction acting between the object and the surface on which the object is rest.

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.

There are fourtypes of friction: static, sliding, rolling, and fluidfriction.
