Static vs Kinetic

What is the difference between Static Friction and Kinetic Friction?

Static friction is the frictional force acting on an object at rest. Kinetic friction is the force when the object is in motion. So you can't have both at the same time.

Static Friction is the force of friction is greater than the applied force. If you apply a little more force, the object "breaks free" and slides, although you still need to apply force to keep the object sliding. This is known as kinetic friction.

Static friction is the force that resists the initiation of sliding motion between two surfaces that are in contact & at rest. Kinetic friction is the force that opposes the movement of two surfaces that are in contact & are sliding over each other. Kinetic friction acts on an object in motion and friction force acts on an object at rest.

Static friction is the force that opposes the sliding motion of an object. Kinetic friction is anything that retards the static friction on an object. An example of kinetic friction is air underneath a hovercraft or a lubricant.

Staic friction is the force that acts on an object at rest. Kinetic friciton is the force on a object at motion. You have both.

Static friction is the force that makes objects resist motion. Kenetic friction is the force that reduces static friction. They are both used in almost every aspect of physics.
