Question

The force of kinetic friction between two surfaces is dependent on the relative speed of the two surfaces.Select one:O TrueO False

Answer 1

The force of kinetic friction between two sliding surfaces depends on the normal force between those surfaces and the coefficient of kinetic friction:

`f_K=\mu_KN`

As we can see, that force does not depend on the relative speed of the two surfaces.

Therefore, the statement is false.
