Tartaglia invented the gunner's quadrant used to determine elevation of the muzzle of a gun. Galileo proved that in a vacuum a projectile describes ... The ballistic pendulum was developed about 1743 by Robins, who was the first to undertake a systematic series of experiments to determine the velocity of projectiles.

A study was done by Leonardo DiVinci on catapults and how to increase the range of their projectiles (~1580). Unfortunately, his knowledge of dynamics was not as good as his analysis of 1804). This result was widely discussed and criticized, until Robins invented a ballistic pendulum apparatus to measure the effect.

CONSERVATION LAWS: THE BALLISTIC PENDULUM ... Perhaps the equipment has insufficient resolution, or perhaps the measuring device hasn’t been invented. Sometimes the equipment isn’t at hand, or it is too expensive. In any case, the scientist has to improvise.

With the advent of the ballistic pendulum, however, all this would change, leading to drastic improvements in all forms of the gun. Gunpowder; Gunpowder, it must be understood, was a relatively recent and under-developed technology in the late 18th century.

Rockets were invented by the Chinese, a spin-off ... He bought some commercial rockets and measured their thrust using a ballistic pendulum, a heavy mass suspended by ropes, to which the rocket was attached. The rocket was fired, and the height to which the pendulum rose provided a measure of the total momentum (mass times...

In 1742 Benjamin Robins, an English mathematician, invented the ballistic pendulum. This device made direct measurements of bullet velocities possible. ... The ballistic pendulum immediately led to two momentous discoveries, (1) muzzle velocities of bullets were much higher than previously thought, and (2) bullets slowed...
