How is geometry used in everyday life? When you’re studying a subject‚ the science of lines and angles can seem like nothing more than a dull exercise in formulas and predictability. In reality‚ geometry is at work everywhere you go. Whether you’re aware of it or not‚ geometry quite literally shapes our lives. An Ancient Science‚ how long has geometry been around? To answer that question‚ let’s take a look at where geometry gets its name. Geometry is derived from the Greek words for Earth (Geo)

Extra Catapult Study Catapults have been used for an extremely long time. The Trebuchet‚ a type of catapult‚ were first created by the Chinese in 300 BC. Catapults were also used in Europe in 500 AD. The Ballista‚ another type of catapult‚ was created by the Ancient Greeks and was also used by the Romans. Still another type of catapult‚ the Mangonel‚ was invented by the Romans in 400 BC. Catapults were extremely important to siege warfare. The French also used Catapults in the 800s. Catapults were

Zac Jordan‚ Ryan Breaux Catapult Project Sharkey Catapults have been used since Greek and Roman times. They were used as siege engines against castles and walled cities. The ammunition loaded into the catapults were meant to break the walls with stones‚ fire incendiary missiles over the walls‚ or used for biological warfare‚ such as launching dead animals over the wall to spread disease. The type of catapult we built is a mangonel catapult. We like to call it RZYAACN (our names combined and

It also seems to have meant a big‚ heavy beam. Today a Trebuchet is any kind of catapult that is powered by a massive counterweight on one end of an arm‚ and a sling on the other end. This includes Perriers‚ or "traction" trebuchets which are powered

The History of the Catapult We usually think of a catapult as something that was used in the Middle Ages to destroy the walls of a castle. But catapults have a very long history dating long before the time of castles and they were developed in many different ways by many different cultures over the centuries. The catapult has been used from ancient times to modern times today. The purpose has remained mostly the same over all these years. Though more recently we have had different ideas for the

A catapult is a device in which accumulated tension is suddenly released to launch an object in a specified direction and distance. Catapults have been used for a long time. They were used as a deadly war weapon. Catapults were first used by the Greeks‚ Romans‚ and the Chinese. They were one of the most effective weapons in war. The first attempts at catapults were to increase the range and power of the crossbow. A Greek historian named Diodorus Siculus was the first to document the use of a

Catapult Report By: Lauren Pernie & Kent Haskett 10/31/2014 3rd Period Physics Blueprint/Design of our catapult. How a Catapult Works: “Catapult physics is basically the use of stored energy to hurl a projectile the payload‚ without the use of an explosive.”1 The entire catapulting process depends on the storing of potential energy as tension of ropes or wooden arm or gravitational potential energy2 “Catapult" is the name given to a variety of related siege weapons used to hurl
