This simple device will help your students visualize their mathematical predictions about circular acceleration. Just spin the apparatus and watch the flat water surface change into a predictable parabolic curve. The speed of the spinning will change the shape of the parabolic curve.To operate simply place water in the chamber, add a little food coloring for effect, spin the device, and watch the flat surface turn into a parabola. The device can be spun by hand or with a rotator if one is available.
Concepts: Uniform circular motion, centripetal force.
Time Required: 10 minutes
Materials Provided: Durable and reusable Liquid Accelerometer Apparatus.
