Kinetic friction also known as dynamic or sliding force is the friction force developed during the motion. The force of kinetic friction is mk times the normal force on a body. Since friction is a force the unit of the frictional force is the newton N.

Why Is Static Friction More Complex In Analysis Than Kinetic Friction. The kinetic friction coefficient is determined during the test by measuring the deflection of the elastic arm or by direct measurement of the change in torque by a sensor located at the pivot point of the arm.
