Vocab:
• Coefficient of friction: The ratio of the
magnitude of the force of friction between
two objects that are in contact with each
other, and the magnitude of the normal force
where the objects press against each other.
The Greek letter ų Mu is used to represent the
coefficient of friction.

Begin the friction lab
Correct the friction lab
H/W P145 Q 1-12 due Tuesday
Correct P145 Q 1-12 Tuesday
Review for the test tomorrow
Test on Wednesday (Sub Day) (Be good!)
Bring a book on test day because the test is
easy, and you need to be quiet during the test.
Friction lab
• Do the lab, and generate a graph of the
normal force versus the force of friction
required to move the object. Graph the Fk of
the block and the mass riding on it. You do
not have to graph the Fsmax, but you do have to
measure it.
• Correct the friction lab
When finished with the lab
• Begin your H/W P145 Q 1-12 due Tuesday.
