Ballistic Pendulum Demonstration for physical science and physics is affordable and works great. Demonstrate the conservation of momentum, calculate the initial velocity of a projectile, or determine the potential energy of a spring.
Finally, an affordable ballistic pendulum that works great too! Effectively demonstrate the conservation of momentum, calculate the initial velocity of a projectile, or determine the potential energy of a spring. Shoot the ball into a pendulum ball to inelastically capture it. The ball and pendulum bob swing to a maximum angle that is registered by a light-weight, counterbalanced pointer. Using the mass of the ball and bob, the maximum angle, and their knowledge of the conservation of momentum, students calculate the initial “muzzle” velocity of the ball. Repeatable, accurate results are achieved quickly and easily. Detailed instructions are included.
