What equation do you use to find the coefficient of kenetic friction
Answered by Ben
The formula is µ = f / N, where µ is the coefficient of friction, f is the amount of force that resists motion, and N is the normal force. Normal force is the force at which one surface is being pushed into another. If a rock that weighs 50 newtons is lying on the ground, then the normal force is that 50 newtons of force. The higher µ is, the more force resists motion if two objects are sliding past each other.

does that equation work for
both kinetic and static friction
Answered by bobpursley
yes, it works for both situations.
