Introduction:
RQ. What is the coefficient of static friction between the felt side of the block
and the aluminum track?
What is the coefficient of kinetic friction between the block and the
aluminum track on an incline?
How does the mass of the block affect the coefficient of static / kinetic
friction?

Method:
1. Determine the maximum angle the block can remain at rest on the incline.
2. Determine the maximum angle the block can remain on the incline with a .25 kg mass attached to
it.
3. Using a velocity vs time graph created by a motion sensor determine the acceleration of the block
on ___degree and ___degree inclines.
4. Using a velocity vs time graph created by a motion sensor determine the
acceleration of a block with an added mass on an ___ and ____ degree inclines.

Conclusions:
1. Draw the free body diagrams of the blocks on the incline both when stationary
and when sliding.
2. Calculate your ___ coefficient of kinetic friction.
3. Compare the coefficient of static friction with the coefficient of kinetic
friction obtained from the previous lab.
4. Create an interactive physics simulation to model the block sliding down an
incline against the force due to friction.
