1M10.20 Pile Driver

Drop weight to drive in nail or crush empty can. Driving in a nail is a standard textbook example of work. In this example PE > KE > Work + Heat.

Setup Requirements: Assembled as needed.

Equations: PE> KE> Work + Heat

Safety Issues: Weight may slip off pulley.

A pendulum is started at a reference line and reaches the same height when a stop is inserted at different places.

Setup Requirements: Off the shelf

Equations: Energy goes back and forth between PE and KE.

Safety Issues: none

1M40.20 Loop the Loop

A ball rolls down an inclined plane and around a vertically oriented circle. Ideally ball will end up at same height it started from. There is some frictional loss in real device.

Setup Requirements: Off the shelf. Remember to return ball.

Equations: Conservation of Mechanical Energy and Centripetal Acceleration.

Safety Issues: none
