Sliding and Stuttering

Ninth graders use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By modifying the bottom surface of the cup, 9th graders can find out what kinds of surfaces generate more or less friction.
