Solution
The maximum static friction is usually greater than the kinetic friction.
Here's why:
-
Static friction is the force that keeps an object at rest from starting to move. It's the friction that needs to be overcome to set the object in motion.
-
Kinetic friction, on the other hand, is the force that resists the motion of an object. It's the friction that acts on the object while it's already in motion.
-
Generally, it takes more force to start moving an object from rest (overcoming static friction) than it does to keep the object moving (overcoming kinetic friction). This is why static friction is usually greater than kinetic friction.
