1G20.70 - Uniform Acceleration - Liquid Accelerometer & Dynamics Cart

Code Number:
Demo Title:
Uniform Acceleration - Liquid Accelerometer & Dynamics Cart
Gravitational Acceleration - Uniform Acceleration
Area of Study:
Pasco Dynamics Cart and Track, Liquid Accelerometer, Acceleration Pulley System.

For visible changes in the accelerometer a 200 g weight should be used.  HOWEVER: This results in an acceleration sufficient to throw the cart off the track if not caught.

Place one or two 4''x 4'' blocks under one end of the track.  Allow the cart with accelerometer to move down the track and notice that the liquid level in the accelerometer is parallel to the track.

The accelerometer in picture three is made for use on the overhead projector.  Fill the cavity with water leaving a small air bubble.  As you spin this in the overhead, the bubble will go towards the center of rotation and not away from it.
