Comprising a set of 3 solid spheres. One each of brass, copper & iron having diameter of 25 mm with a small ring for suspension.
The pendulum bob provides one of the necessary tools for studying the physics of pendulum motion (tension force, gravity force, centripetal force, potential energy, kinetic energy, oscillations, simple harmonic oscillations, etc.). When used with a full pendulum set up, it provides a visually and kinesthetically effective method by which to study pendulum physics.
Works well with Eisco pendulum clamp (Code: PENDUCLP).
