1M 10.25 - Pile Driver

Demonstrates: Work.
Description: Lead brick pile driver smashes aluminum can.

1M 40.10 - Nose Basher

Demonstrates: Conservation of energy.
Description: 25Kg. bowling ball is suspended from ceiling, brought up against face and released.

1M 40.17 - Simple Pendulum

Demonstrates: Conservation of Energy.
Description: At the lowest point of its swing, all of the gravitational potential energy Utop that was stored in the pendulum in raising it to the top of its swing gets converted to kinetic energy Kbottom.

1M 40.20 - Loop the Loop (Large)

Demonstrates: Angular momentum.
Description: Aluminum track bent around itself to form a loop in the middle with one end angled to be used as a starting point for a steel bearing to be rolled down. The opposite end has a tube to stop the ball after release.

1M 40.25 - Loop the Loop (Small)

Demonstrates: Potential and kinetic energy.
Description: A smaller version of the large loop the loop that has its own catch box.

1M 40.30 - Ninja Balls - Elastic Collisions

Demonstrates: This demonstration may be used to motivate calculations of elastic collisions between differing masses. It is also useful to demonstrate the use of a “gravitational slingshot” or gravity assist to boost a spacecraft’s speed.
Description: When the stack of balls is dropped, the top ball bounces significantly higher than its starting position (a drop of only about 2 feet is sufficient to send the top ball almost to the ceiling of Regener 103). The elastic collision of the descending top ball with the rebounding, larger lower balls is symmetric in the center-of-mass frame, but this frame is moving upward rapidly.

1M 40.41 - Ballistic Pendulum

Demonstrates: Conservation of energy.
Description: A drilled brass ball is fired by a spring gun into a catcher cup that is suspended as a pendulum. The kinetic energy of the ball drives the pendulum upward where a rack and prawl hold it at its highest point.

1M 40.50 - Big Yo-Yo

Demonstrates: Conservation of energy.
Description: Big Yo-Yo.

1M 40.67 - Energy in a Spring

Demonstrates: Potential and kinetic energy.
Description: The difference between KE and PE is shown by masses in motion or sitting on the compressed spring.

1M 40.90 - Rattleback

Demonstrates: Conservation of energy.
Description: Rattleback (large).
