Eisco® Pendulum Bobs, with Hook

Simple metal bobs each come with a hook for easy attachment to pendulum.

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, etc.). When used with a full pendulum set up, it provides a visually and kinesthetically effective method by which to study pendulum physics. With different sizes and materials, you can demonstrate the independence of a pendulum's motion from the mass of its bob.
