If the coefficient of kinetic friction between the 100-n block and the table is 0.250, 50.0-n weight to allow the system to move at a constant speed 50 N should replace by 25N.

A force that acts between moving surfaces is referred to as kinetic friction. A force acting in opposition to the direction of a moving body on the surface is felt. The two materials' coefficient of kinetic friction will determine how much force is applied. Constant speed refers to a motion that has a constant pace throughout the entire motion. Constant speed is demonstrated in our example of cruising in an automobile. If there is no force exerted on a body, it will travel at a constant speed. Kinetic friction has the following formula: . The two main types of friction are sliding friction and rolling friction.
