Code Number: 1M40.15
Demo Title: Stopped Pendulum
Condition: Excellent
Principle: Potential to Kinetic Energy, Simple Harmonic Motion
Area of Study: Mechanics
Equipment:
Stopped Pendulum.
Procedure:
The pendulum should be set with a variable right angle clamp holding the stop rod. Practice will be needed so that the stop rod can be turned into place at the proper time of the pendulum motion.
