Measuring the Velocity of an Object Using the Ballistic Galvanometer
























ABSTRACT:
The objective of this lab is to prove the conservation of energy and momentum by comparing initial velocities of two different experiments using the Ballistic Pendulum method. To conduct this method, a ballistic galvanometer was used to measure the velocity of a metal ball in an inelastic collision and in projectile motion. The ballistic galvanometer consists of pendulum with a holding chamber at the bottom of the pendulum arm. Across from the arm is a metal holder where the ball is positioned, pushed back, and launched from. Once the ball is launched, it shoots directly into the chamber of the pendulum with an initial velocity (V ), and swings back to the top of the galvanometer at a higher position. The pendulum is stopped from coming back down when it swings back by a grooved, rubber padding that catches onto the chamber. This method described above ...
