Question

How many types of friction are there?

Answer 1

There are two types of friction :
(i) Static friction: This type of friction acts till the body does not move, therefore this type of friction is known as static friction. The maximum static friction is known as “Limiting friction”.

(ii) Dynamic or kinetic friction: When the body starts moving, then the acting friction is known as dynamic or kinetic friction. Its value is some less than the limiting friction.
