# Rotational Dynamics

## D3-33: Centripetal Acceleration - Rotating Ball and Brick

Purpose: To illustrate centripetal acceleration and the associated forces

## J5-30: OMEGA LEVITRON

Category: J5 Magnetostatics
Purpose: Show an interesting demonstration of magnetism.

## G3-20: WAVE APPARATUS

Purpose: Demonstrate transverse and longitudinal wave motion.

## G1-12: PENDULUM AND ROTATING BALL

Purpose: Demonstrate that simple harmonic motion is the projection of uniform circular motion.

Category: F4 Fluid in Motion
Purpose: Illustrate the reaction force on spinning water and the shape of the water surface.

## F4-21: LIQUID IN SPINNING SPHERE

Category: F4 Fluid in Motion
Purpose: Show the behavior of a liquid when subjected to a centripetal force.

## D5-24: ROTATING PENDULA - LENGTH VS. HEIGHT

Purpose: Show that pendula of different length suspended from the same point rotating at the same angular speed rise to the same vertical height.

## D5-23: ROTATING BEAD ON LOOP

Purpose: Demonstrate the presence of a "critical parameter" which determines the dynamic behavior of a simple physical system.

## D5-22: ROTATING PENDULUM

Purpose: Demonstrate the presence of a "critical parameter" which determines the dynamic behavior of a simple physical system.

## D5-21: BALL ROLLING ON ROTATING DISC
