Can frictional force ever be greater than the applied force?

 

[Cawolf]

No.

If the object isn't moving then the static frictional force is equal to or less than the applied force.

If the object is moving, then the kinetic frictional force is less than the applied force (assuming the object's velocity is in the direction of the applied force, such as linear motion).

I tend to think of them this way: The kinetic and static frictional forces are always some portion of what the normal force would be. What he said above as well 🙂
