PIRA Code(s): 1L20.40 Set up time:5 minutes Operation: Remove pieces from the cone to show different conic sections. Physics and Science Concepts: Gravity Safety: Nails that connect pieces may be sharp.
PIRA Code(s): 1M40.10 Set up time:5 minutes Operation: Hook the bowling ball onto the chain. Pull the bowling ball back until it reaches your nose. Release the ball and do not move. Let the ball come back and show how it will not reach your nose again. *For use in lecture room 131. Physics and Science Concepts: Mechanics, Work and Energy Safety: Do not give the ball an initial velocity or move forward once the ball is release. Warning: it’s hard not to flinch.
PIRA Code(s): 1M40.20 Set up time:none Operation: Place ball at the top of track and let it fall. To show students the minimum height required to loop the loop, place the ball on the track at a height that is about double the height of the loop. Physics and Science Concepts: Mechanics, Work and Energy, Conservation of Energy, Centripetal Force Safety: Do not stand where the ball exits the track.
PIRA Code(s): 1Q40.40 Set up time:5 minutes Operation: Place the train on the track. Plug the track into the variac and start the train by moving the dial. Physics and Science Concepts: Mechanics, Angular Momentum, Rotational Dynamics, Angular Momentum, Relative Motion Safety: Watch for sparks from the train. Maintain a cautious distance from the wheel.
