Bell Ringer: Write a question that could appear on Monday's test. If I like your question enough to use it on the test, you'll receive 5 bonus points. (hint: I'm just a TINY bit goofy, and tend to like some of the sillier questions that still test over the material we've learned)
Review inclined plane problems
Work inclined plane examples
Finding the coefficient of friction using inclined planes
Place a weight on a plane that can be tilted upward
Slowly increase the angle of the plane until the weight just begins to slide
Measure the angle that the plane makes with horizontal
Measure the weight of the weight (that sounds strange)
Calculate the component of the weight that acts parallel to the plane at that angle, this is equal to the force of friction just before the weight begins to slide
Calculate the component of the weight that acts perpendicular to the plane at that angle, this is equal to the normal force.
Use the force of friction equation to find the coefficient of friction between the weight and the inclined plane.
