Wa-10 Simple Harmonic Nature of Circular Motion
Aim
To demonstrate that circular motion is sinusoidal in nature.
Apparatus
- Turntable
- Billiard Ball
- Video Camera x2
- Video Splitter
Description
A billiard ball is attached to the edge of a turntable with a piece of blue tac. Two video cameras are placed directly above and side on to the turntable. The vision from the video camera above the turntable will display the billiard ball to have circular motion. While the vision from the side on video camera the billiard ball will appear to be purely sinusoidal. A video splitter can be utilised to display the vision from both video cameras simultaneously.
