Physics Demo Manual

Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

video  - Contact Area Independence of Friction Purpose: To demonstrate that the kinetic (and minimal static) coefficient of friction does not depend on the area of contact.

Adjust the plane's angle so that the block is just barely moving or requires a minimal nudge to go. Flip the block over so that the area is half(twice) the original and demonstrate that the block is still barely moving without acceleration. Hints: Brass plate needs to be polished. Wooden block should be inspected on both sides to have similar surface smoothness.
