What is kinetic friction?

Kinetic friction is a force that slows down moving objects. It is created when two surfaces slide past one another, and it always acts in a direction opposite the direction the object is moving.

What is the difference between static and kinetic friction?

Static friction is the friction force that acts on objects that are not moving. It is the force that keeps things from moving. Kinetic friction is the friction force that acts on objects that are already moving. It acts to oppose the motion and slow the moving object down.

How do you calculate static and kinetic friction?

You calculate kinetic and static friction forces using similar equations. The coefficients of friction are different, however.
KINETIC friction force = coefficient of KINETIC friction X normal force
STATIC friction force = coefficient of STATIC friction X normal force

What are some examples of kinetic friction?

Whenever two surfaces slide past each other, there is kinetic friction. Kinetic friction is produced when brakes are applied to tires, when an object like a box slides across the ground, or when sandpaper is rubbed across a surface.

What is the kinetic friction formula?

The kinetic friction formula is an equation used to calculate the kinetic friction force acting on a moving object. It depends on the coefficient of friction and the normal force exerted on the object by the surface it is moving on.
Friction force = coefficient of friction X normal force

What is the coefficient of static and kinetic friction?

The coefficients of static and kinetic friction are unitless numbers that are used to calculate static and kinetic friction forces. For any two materials, the coefficient of static friction is always bigger than the coefficient of kinetic friction because it takes more force to start an object moving than it does to keep it moving.
