Students in physics performed a lab called The Ballistic Pendulum, in which they used newly purchased lab equipment to launch steel balls into a pendulum cup. Using the principles of conservation of energy and conservation of momentum, the students were able to calculate the velocity of the steel ball as it left the launcher. They then applied dynamics to predict the range that the launcher would fire the steel ball, and tested this in the hallway by firing the ball horizontally off a desk and having it leave a mark on a sheet of paper.

In the first photo, physics students, Ryan Harman and Neill Baker, are making measurements with the pendulum in lab. In the second photo, Ginell McLean is launching the projectile in the hallway. If you look closely you can actually see the faint arc of the projectile as it passes!
