PURPOSE: To demonstrate simple harmonic motion of a mass held by two springs.
DESCRIPTION: The center (moveable) glider, connected by springs to two fixed gliders (taped to air track), executes SHM about its equilibrium position when displaced and released. Additional weights can be added to the oscillating glider to increase its period.
REFERENCES: (PIRA 3A20.35)
EQUIPMENT: Air track, three gliders, springs, weights, and timer.
SETUP TIME: 5 min.
