Purpose To illustrate various concepts of circular motion. Parts All parts are found on shelf D3. Crank to transfer hand motion into bit rotation Various attachments… Continue reading »

Two-body system

Purpose May be used to demonstrate the principle of center of mass and circular motion Parts The two-body system is found fully-assembled on shelf C3. Setup No setup required. simply twirl the system as in the photo below to illustrate concepts of center of mass and circular motion. Continue reading »

Rotating Platform

Purpose: Conservation of Angular Momentum. Parts: Rotating platform Weights Bicycle wheel Setup: Keep the platform on the floor, let a volunteer stand on it(feet should spread out and align the body so that the center of mass is right over the center of mass of the platform). Continue reading »

Loop the loop

Purpose This demonstration may be used to illustrate the concepts involved in circular motion. For example, one can perform a calculation to determine the minimum height of release required for the steel ball to make it through the loop. Parts All required parts other than ring stand are found on… Continue reading »
