  • Equilibrium of Forces – Inclined Plane
    PIRA Code(s): 1M20.30
    Set up time:5 minutes
    Operation: Set the empty friction box on the incline with weights attached to the string on the other side of the pulley so that the box slides forward. Then, gradually increase the angle of the plane until the box and the weights reach equilibrium.

  • Fluorescent Lamp Circuit
    PIRA Code(s): 5L20.14
    Set up time:1 minute
    Operation: Plug in the circuit. Flip the switch that says line and then put the lever to the automatic side for the whole lamp to light up. Flip the line switch again and move the lever to the middle. Put the line switch on again and move the lever to the manual side. This will heat up the filament. Then move the lever a little away from the manual side for the entire light to be lit.
    Physics and Science Concepts: AC Circuits
    Safety: None
