Question

what is friction force of a ball​

Answer 1

Answer:

A ball can slip on a surface, can roll, or both. A ball slipping on a surface is decelerated by the friction force opposing the ball linear displacement. ... The kinetic friction coefficient (and thus the force) is independent of the velocity of the ball, within certain limits (some cm/s up to several m/s)

please mark this the brainliest

Answer 2

Answer:

A ball slipping on a surface is  decelerated by the friction force opposing the ball linear displacement. The friction  force provides also angular momentum to the ball, which starts rotating until it  rolls on the surface without slipping. When the ball is slipping, we have kinetic  friction between the ball and the surface; when it is rolling we have rolling friction  between the ball and the surface.
