# What is the science behind a catapult?

A catapult works because energy can be converted from one type to another and transferred from one object to another. … This energy is stored in the launching device as potential, or stored, energy. The catapult you are about to make uses elastic potential energy stored in a wooden stick as you bend it.

## In this manner, does the angle of a catapult affect the distance?

The angle at which the throwing arm is pulled back to will affect both the distance the projectile will travel and also the height that it reaches when in the air.

Thereof, how are catapults used today? Catapults evolved from simple slingshots to siege weapons. Today, catapults can be used to launch airplanes from aircraft carriers, or to demonstrate physics and mathematics to students.

## Beside above, how do you explain a catapult to a child?

A catapult is a type of machine used as a weapon to throw rocks or other things such as hot tar, that would cause damage to something else. Often, catapults were set on higher ground or on castle towers to let them shoot farther. They shot rocks to break castle walls, or pitch or hot tar to set the target on fire.

## What can you learn from a catapult?

Students learn about catapults, including the science and math concepts behind them, as they prepare for the associated activity in which they design, build and test their own catapults. They learn about force, accuracy, precision and angles.

## What makes a catapult go farther?

Wind the string or rope tighter. Put a piece of wood across the base of the catapult to keep it strong, so you can wind even tighter. Lengthen the swing arm of the catapult or move the cup up or down the length to different spots. Move the crossbar up or down, or add pieces of wood to it to change the trajectory angle.
