What Is Kinetic Friction?
Kinetic friction refers to the frictional force of a moving object. If a force is being applied on a stationary object, friction is considered a static force until movement occurs.
Friction is a force that occurs between two or more surfaces of objects that is typically in the direction opposite to the force being applied on an object. It can be calculated by multiplying the coefficient of friction by the normal force, which takes into account gravity and any other forces perpendicular to the surfaces in contact. The static coefficient of friction is used when the object is stationary, and is usually larger than the kinetic coefficient of friction, which is used during movement.
