Ballistic Pendulum TLS-46ma


In this experiment, first a bullet is thrown toward the ballistic pendulum by a projectile. Then the bullet strikes the pendulum and moves this part into a definite angle. We can investigate the conservation of energy in this collision.

This apparatus is used along with a projectile apparatus which has a spring that can causes different velocities.
