The kinetic friction force is equal to the product of the coefficient of the kinetic friction and the normal force
What is friction force?Friction force define as the force that resisting the relative movement of fluid layers, solid layers, and material elements sliding against one another. There are two type of friction that connected with the value of the normal force, they are:
Kinetic friction force is a friction force that happen when an object is moving. It has the value equal to coefficient of kinetic force multiply with normal forceStatic friction force is a friction force that happen when an object is not moving. It has the value equal or lower than the value of coefficient of kinetic force multiply with normal forceLearn more about friction force here
