Ballistic Pendelum In Stock Now

The ballistic pendulum is a classic in the Physics lab with an impressive military history. Its premise had long been known by the makers of munitions. Invented in 1742 by Benjamin Robins to measure the speed of bullets, he soon realized that, by knowing the weight of the pendulum with its target, the weight of the shot fired, and the distance the pendulum moved when struck, he could calculate the velocity of the shot. By performing experiments at various distances, he was also able to determine the effects of air density and gravity as the range increased.
