Kinetic Friction
 
Opposite of the relative motion between objects
to the surface
Static Friction
 
Kinetic friction
= coefficient of kinetic friction
Static friction
should be slightly larger than
= coefficient of static friction
Example 1: A string is attached to a block and the block is pulled to the right with a horizontal tension force
of . While this force is applied, the block slides with a constant speed of . What is the kinetic
friction on the block?
