Mechanical Engineering students - Clemson University

This science experiment apparatus built by Mechanical Engineering students utilizes a PDT to help demonstrate forces and motion experiments to local 2nd graders.  They are shown the effects of weight (heavy or light blocks), friction (smooth or sandpaper blocks) and the height of ramps on the time taken for the blocks to reach the bottom of the ramp.
