Catapulting though Time & Physics Essay example -- Essays Papers
Catapulting though Time & PhysicsHurling an object towards mavins enemy may seem as old as time itself. People befool hurled fists at each other, thrown spears, and launched colossus rocks into enemy territory. The use of catapults, and other objects that hurl projectiles, also seem as old as human civilization itself. The effectiveness of the catapult in flinging objects over a great distance and causing destruction is delinquent to a few basic physics principals that govern force, energy, motion, speed and concourse to name a few. The intent of the catapult denotes a change in modern warfargon to the engineer behind weapons being just as important as the actual soldiers and people who use them. Projectile-throwing machines be comprise in three main categories the catapult, the arbalest, and the trebuchet (How binge Works).

The ballista is basically a giant crossbow and the trebuchet is similar to the catapult besides is a weighted beam with a sling carrying the projectile (How Stuff Works).
