C4-11. Accelerometer - Ball In Water
Purpose
To demonstrate the direction of acceleration for both linear and circular cases.
Equipment
Water-filled plastic tubes with pingpong balls, as photographed.
Images
Description
When the accelerometer is accelerated linearly, the pingpong ball, being less dense than the water, moves toward the direction of the acceleration. When the jars are rotated the pingpong ball moves toward the center of rotation.
