types of friction....
Answers
Answer:
THERE ARE THREE TYPES
OF FRICTION :-
a) Static friction:-
✔ The Frictional force that comes into play until an object starts moving is called static Friction. When a body is at rest. the force of friction is called the static friction and is always equal and opposite to the applied force.
✔ An object has to overcome the static Friction force in order to start its movement.
b) Sliding friction:-
✔ The frictional force present when one object slides over the surface of another object is known
as sliding friction.
✔ When the object is in motion or sliding, the irregularities of the moving object doesn't get enough time to interlock with the irregularities of the surface.
✔ So, sliding friction is always less than static friction.
c) Rolling friction:-
✔When an object rolls over the surface of another object, then the frictional force that comes into picture is called rolling friction.
✔ Rolling friction is less than sliding friction.
