Purpose: Demonstrate operation of the standard laboratory type ballistic pendulum.
Description: 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.
Availability: Available, but not currently recommended.
