⤵⤵Answer⤵⤵

The coefficient of kinetic friction is typically denoted as μk, and is usually less than the coefficient of static friction for the same materials.The friction force between two surfaces after sliding begins is the product of the coefficient of kinetic friction and the normal force .

Answer 2

Explanation:

The coefficient of static friction (Us):

It is define as the limiting friction to normal reaction.

The coefficient of Kinetic friction :

It is define as the ratio of kinetic friction to normal section.

And Coefficient of kinetic friction is generally smaller than Coefficient of static friction.
