Demonstrates: Period of oscillation is independent of gravity.
Description: Oscillate by perturbing the cart from equilibrium. As you tilt the track, the cart should continue to move with the same period. This shows that the period of oscillation is independent of gravity.
Instructions: Move the cart from equilibrium so that it starts oscillating. Start tilting the track until vertical (or nearly vertical).
Items Used: Motion cart, 2 springs, motion cart track
