Show the surprising effect of an impulse load on a large inertial mass.
- Use as an inertial mass or a large pendulum bob
- Powder-coated iron sphere
This powder-coated iron sphere may be used to demonstrate the effect of an impulse on a massive object. Suspend the sphere with a light cord using the top and bottom eye hooks. First jerk down hard on the lower cord until it breaks. Then, replace the cord, but pull down slowly and gently. The results reveal worlds about inertia! Alternatively, the spehere can be used as a massive pendulum bob for exciting demonstrations of harmonic motion and conservation of energy.
The sphere comes with two eye hooks mounted opposite each other, and a third eye hook for a safety line. The eye hooks can be removed if desired. Color and texture may vary slightly.
