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): 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.
PIRA Code(s): 3A10.40 Set up time:none Operation: Push the pendulum so that it swings back and forth at an angle of about 0 º. Then, slowly increase the angle, and watch the frequency decrease. For a more effective demonstration, start the pendulum at a relatively high angle, and then decrease the angle of the plane of oscillation so that the frequency of the pendulum will increase over time. Physics and Science Concepts: Oscillations Safety: None
