Which of the following is true about kinetic or dynamic friction?

The kinetic friction coefficient is the same as the static friction coefficient.
The kinetic friction coefficient is greater than the static friction coefficient.
The kinetic friction coefficient is less than the static friction coefficient.
The kinetic and static friction coefficients are both used at the same time.
Most objects do not have a kinetic friction coefficient.

Explanation

Answer: C - The kinetic friction coefficient is always less than the static one for two objects interacting. The kinetic friction coefficient is used when the two objects are sliding, and the static one is used when the objects are at rest.
