Attach a ball and string to a vertical support. Use this simple pendulum to describe periodic motion.
Location: Ball/string –
C2-10-2
Vertical support – C2-08-2
Prep time: 1 minute
Place a horizontal bar in the path of a simple pendulum. The ball will still return to its original height.
Location: Ball/string –
C2-10-2
Vertical support – C2-08-2
Horizontal bar – C2-11-3
Prep time: 1 minute
This is a demo with two pendulums. One pendulum has a string length of one meter. The other pendulum has a string length of ¼ meter. Releases both pendulums at the same time. For every two oscillations the short pendulum goes thorough the large pendulum goes through one oscillation.
Location: Pendulums -
C2-12-2
Vertical support - C2-08-2
Prep Time: 2 minutes
Use a Torsional pendulum to demonstrate periodic motion.
Location: Torsional pendulum - C2-13-2
Vertical support - C2-08-2
Prep Time: 2 minutes
Use a mass on a spring to demonstrate periodic motion.
Location: Mass on a spring -
ME1C-34-1
Prep Time: 2 minutes
Use a graduated cylinder filled with water to dampened a mass on the spring. The damping is very nearly critical.
Location: Mass on a spring - ME1C-34-1
Graduated cylinder - ME1C-35-2
Prep Time: 3 minutes
Use a pendulum and the small clamp provided. Pass the string through the hole in the clamp. Holding the free end of the string, start the pendulum swinging. When it reaches its equilibrium point. Pull on the sting and the amplitude of the pendulum will increase.
Location: Pendulum -
C2-12-2
Clamp -
C2-14-3
Vertical Support - C2-08-2
Prep Time: 3 minutes
Use this video to demonstrate resonance.
Location: Film loop - AV5-01-1
Projector - AV3-02-1
