Experiment 1: Damped Oscillation
Set-up
1. Set up the equipment as illustrated. Use two or three weak springs combined
end-to-end.
Experiment set-up for Damped Oscillation
2. Adjust the angle of the track (or the position of the end stop) so that the cart’s
equilibrium position is about 40 cm from the lower end of the track.
Method I (without sensors)
Skip to Method II if you will be using a motion sensor.
1. Place the Magnetic Damping Accessory on the end of the cart with a gap of
10 mm between the magnets and the track.
2. Tap the cart a few times so that it moves to its equilibrium position.
3. Pull the cart up the track and hold it 20.0 cm from equilibrium.
