Ballistic Pendulum - Laboratory Model
To demonstrate operation of the standard laboratory type ballistic pendulum.
Ballistic pendulum, as photographed.
A heavy ball is placed on the compressed spring, as shown in the photograph, and released by pulling the trigger. The ball fires into a catch on the bob of a physical pendulum, causing the bob to swing to a large angle, where it is caught by a ratchet system. Due to lack of time, this device is generally demonstrated only qualitatively during regular class lectures. Appropriate condiments can be delivered if complete measurements are desired.
