Kinetic Friction

Kinetic friction is the force that opposes the motion of two surfaces sliding against each other. When an object moves, such as a box being pushed across a floor, kinetic friction acts in the opposite direction of the movement. This force depends on the materials of the surfaces in contact and how rough they are, as well as the weight of the object. While it allows for controlled movement, kinetic friction can also slow down or stop an object. Understanding it is essential in various applications, from engineering to everyday tasks like walking or driving.
