Newton's cannonball was a thought experiment Isaac Newton used to hypothesize that the force of gravity was universal, and it was the key force for planetary motion. It appeared in his posthumously published 1728 work De mundi systemate (also published in English as A Treatise of the System of the World ).
The casualties from round shot were extremely gory; when fired directly into an advancing column, a cannonball was capable of passing straight through up to forty men [citation needed]. Even when most of its kinetic energy is expended, a round shot still has enough momentum to knock men over and cause gruesome injury.
Round shot or solid shot or a cannonball or simply ball A solid spherical projectile made, in early times, from dressed stone but, by the 17th century, from iron. The most accurate projectile that could be fired by a smooth-bore cannon, used to batter the wooden hulls of opposing ships, forts, or fixed emplacements, and as a long-range anti ...

Cannonball concretions are large spherical concretions, which resemble cannonballs. These are found along the Cannonball River within Morton and Sioux Counties, North Dakota, and can reach 3 m (9.8 ft) in diameter. They were created by early cementation of sand and silt by calcite.
A certain amount of windage (in this case meaning that the bore is designed slightly wider than the cannonball) allows the ball to fit down the bore, though the greater the windage the less efficient the propulsion of the ball when the gunpowder is ignited. To fire the cannon, the fuse located in the vent is lit, quickly burning down to the ...
In April 1877, the 17-year-old Richter became known in Europe as the first human cannonball, performing as "Zazel, the Beautiful Human Cannonball," [8] [11] [14] although Hunt's son "Lulu" had been performing the human cannonball act since 1873. [15] The Mackay Mercury wrote that the event "hurled her from the jaws of death into the arms of fame."
On December 6, 2011, while taping for the "Cannonball Chemistry" story, a home-made cannon test sent a cannonball through a residential neighborhood in Dublin, California. No one was injured, but the cannonball did considerable property damage, crashing through the walls of a family's house and landing in a car. [2] [3]
