Question

How do kinetic friction and static friction compare when pushing on a box?(1 point)
Responses

Static friction is the same as kinetic friction, but the momentum of the box makes it require more force to start moving the box than to keep moving it.
Static friction is the same as kinetic friction, but the momentum of the box makes it require more force to start moving the box than to keep moving it.

Static friction is always greater than kinetic friction, so it requires more force to start moving the box than to keep moving it.
Static friction is always greater than kinetic friction, so it requires more force to start moving the box than to keep moving it.

Static friction is less than kinetic friction, so it requires less force to start moving the box than to keep moving it.
Static friction is less than kinetic friction, so it requires less force to start moving the box than to keep moving it.

Static friction is the same as kinetic friction, so it requires the same force to start moving the box and keep moving it.

The correct response is:

**Static friction is always greater than kinetic friction, so it requires more force to start moving the box than to keep moving it.**

Static friction must overcome the initial resistance to motion, which is usually higher than the resistance encountered once the object is in motion (kinetic friction).
