A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. [1]

2025年1月14日 · Catapult, mechanism for forcefully propelling stones, spears, or other projectiles, in use mainly as a military weapon since ancient times. Nearly all catapults operated by a sudden release of tension on bent wooden beams or of torsion in …

2023年9月19日 · Catapult arm: The catapult arm is the long wooden beam or lever that holds the projectile. It is the part that moves when the catapult is fired. Tension: Tension, often created by twisted rope or other means, stores the energy required to launch the projectile.

2025年1月26日 · Test your catapult by pulling back the arm and releasing it. Adjust as needed for optimal performance. Note: Always practice safety precautions when building and using a catapult. Keep it away from faces and eyes, and never aim it at people or animals. Conclusion. The catapult, a symbol of ancient ingenuity, continues to inspire and captivate.

Catapult physics is basically the use of stored energy to hurl a projectile (the payload), without the use of an explosive. The three primary energy storage mechanisms are tension, torsion, and gravity. The catapult has proven to be a very effective weapon during ancient times, capable of inflicting great damage.

2020年2月1日 · The basic design of a trebuchet is a lever, with a short arm facing the enemy and a longer arm being the business portion; an axle separates the two. A counterweight is applied to the shorter arm to add force at the point the projectile is released from a sling. This catapult comes in two forms.

2020年11月21日 · A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants. A catapult uses the sudden release of stored potential energy to propel its payload.

2023年5月17日 · Catapults operate using projectile motion, which is a form of science called Physics. Catapult physics is basically the use of stored energy to hurl a projectile (the payload). The three primary energy storage mechanisms are tension, torsion, and gravity. How do you build a catapult for a physics project?

First appearing in the 4th century BC the catapult was designed to easily increase the effective range of armies to allow for prolonged sieges and engagements over defensive walls. Out of all the designs for catapults, there are 3 categories they all fit into. Catapults changed how warfare was fought for over 1,700 years.

In this science project, you will use a catapult to launch ping-pong balls and use a video camera to film their trajectory, or path, as they fly through the air. You can also use physics to predict the trajectory of the ball, and then compare this predicted trajectory to the one you measure from video recordings.
