## How does catapult relate to science?

A catapult works because energy can be converted from one type to another and transferred from one object to another. When you prepare the catapult to launch, you add energy to it. This energy is stored in the launching device as potential, or stored, energy.

## What is the hypothesis for a catapult?

The hypothesis was that the more rubber bands placed on the catapult the farther the ball would launch. The results of this experiment are inconclusive, because in the second trial the ball went less distance with the addition of one band.

What are 5 types of catapults?

There are five historical types of catapults: the mangonel, onager, ballista and trebuchet, using three types of motive force: tension, torsion and gravity.

### How do you make an easy catapult?

Simple craft stick catapult:

1. Stack five craft sticks together and wrap a rubber band around each end.
2. Stack two craft sticks and wrap a rubber band around only one end.
3. Slide the five sticks in-between the two sticks, as shown.
4. Wrap a rubber band where the two sections meet to hold the catapult together.

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.

#### When catapults were first used as weapons?

Catapults were invented by the ancient Greeks and in ancient India where they were used by the Magadhan Emperor Ajatshatru around the early to mid 5th century BC.

How does mass affect the distance of a catapulted object?

Objects with greater masses are found to be affected more by gravity, and therefore don’t travel as far when launched. Also, as shown by Newton’s Second Law of Motion, if two objects are given the same force, the lighter object will accelerate more, and therefore cover more distance.

## What are some science projects you can do with a catapult?

Paper Rocket Aerodynamics: explore the design of a straw-blown paper rocket and the variables that affect its flight. Build a Popsicle Stick Catapult: build and experiment with a simple catapult made from wooden sticks and rubber bands to explore the physics at work in a catapult.

## What was the purpose of the catapult in ancient times?

Since ancient times, catapults have been iconic of siege warfare. A marvel of military innovation, catapults can still teach us a lot about engineering, physics, and history. Read on for ways you can bring the power of the catapult to your own science fair project. Torsion Vs. Traction Catapults

How to use a catapult to storm a castle?

Under Siege! Use a Catapult to Storm Castle Walls: explore the settings on the Ping Pong Catapult that control whether the ball will fly into into a castle wall or over it.

### What can you do with a rubber band Catapult?

Using a rubber-band-powered catapult you will send ping pong balls flying through the air. The catapult’s design makes it easy to measure and repeat how hard the ball is launched and its direction, so you can find the right catapult settings to hit the target reliably. Read more
