Collision - Dynamics. In physics, collision means the action of bodies striking or coming together (touching). Collisions involve forces (there is a change in velocity). Collisions can be elastic, meaning they conserve energy and momentum, inelastic, meaning they conserve momentum but not energy, or totally inelastic (or plastic), meaning they conserve momentum and the two objects stick together. The magnitude of the velocity difference at impact is called the closing speed. The field of dynamics is concerned with moving and colliding objects. ...

An aircraft carrier is a warship whose main role is to deploy and recover aircraft—in effect acting as a sea-going airbase. Aircraft carriers thus allow a naval force to project air power great distances without having to depend on local bases for land-based aircraft. Modern navies, who operate such ships, treat aircraft carriers as the centerpiece of the fleet, a role previously played by the battleship. The change, part of the growth of air power as a significant part of warfare, took place during World War II. Unescorted carriers ...

An anti-personnel weapon is one primarily used to injure or kill people. While the distinction is very old—a spear is anti-personnel, while a catapult is of more use against buildings than individuals—the large-scale development of military technology in the 19th and 20th centuries has made the concept a key consideration in design. For instance, an anti-personnel landmine will explode into small and sharp pieces of shrapnel that tear flesh but have no effect on metal surfaces, and w ...

Buhen was an ancient Egyptian settlement situated below the Second Cataract. It is well known for its fortress, probably constructed during the rule of Sesostris III, around the year 1860 BC (12th dynasty). The site may have been first established as an outpost in Nubia during the reign of Sneferu (4th dynasty). Grafitti and other inscribed items from the site show that the Egyptians stayed about 200 years, until late in the 5th dynasty, when they were probab ...

A CAM ship was a World War II-era British merchant ship used in convoys as a quick emergency solution to the shortage of escort carriers. "CAM" was an acronym for "Catapult Aircraft Merchantman" and a CAM ship was equipped with a rocket-propelled catapult launching a single Hawker Sea Hurricane, dubbed a "Hurricat" or "Catafighter". The ship was not fitted for landings so the pilot would bail out or ditch in the sea at the end of the flight and the plane would be lost. In 1940-41 35 ships were converted, starting with SS Michael E, and continued ...

The ballista (Latin, from Greek ballistēs, from ballein "to throw", plural ballistae) is a powerful weapon resembling a giant crossbow, to eject heavy darts singly or in groups. It is also sometimes referred to as a bolt thrower. The first ballistae were deployed in Ancient Greece, and were mainly large crossbows fastened on a mount. The first known appearance was in Syracuse, in Sicily, around 400 BC. Rom ...

Military history of India - Indus Valley Civilization. The amazing uniformity of measurement systems across a number of sites suggests that Indus Valley Civilization was a single state. However, it seems that the large cities were controlled by small groups of merchants, landowners and priests. Therefore, no standing armies were involved. The artifacts and texts from contemporaneous Egypt and Mesopotamia clearly depict battles. But the excavations at Harappan sites have not revealed a single artifact that depicts ...

The types of tube artillery are generally distinguished by their ballistic trajectory. Cannons or guns (such as infantry support guns or those on a naval ship) are typically longer-barreled, low-trajectory weapons designed for a direct-fire role. Typically the length of a cannon barrel is greater than 25 times its caliber (inner diameter). Howitzers are typically shorter- and thinner-barreled. Capable of both high- and low-angle fire, they are most often employed in a close indirect-fire role, operating in defilade. Typically the length of a howitzer barrel is b ...

The mangonel as described here is a medieval version of an Ancient Roman catapult nicknamed the onager. This was a single-arm torsion catapult that held the projectile in a sling. A similar and perhaps older device was nicknamed the scorpion because of its resemblance to a scorpion's tail and sting. The onager's power is derived from twisted sinew ropes, similar to those in a ballista, but an onager has only one arm while the ballista has two. The Romans greatly improved the onager's maneuverability by adding wheels to its base. The wheels and the onager' ...
