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.
Agenda • 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.
