A catapult is a ballistic device used to launch a projectile a great distance without the aid of explosive devices—particularly various types of ancient and medieval siege engines.
What is a catapult used for 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 was a catapult used and for what purpose?
The catapult was a special type of siege engine, a large device used to attack a fortress or a city. Catapults were used in ancient and medieval warfare until the introduction of the gunpowder cannon in the 14th century.

What were catapults used for kids?
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.

In medieval times, catapults were used as siege weapons and designed to launch objects over castle walls. Some of these objects were what you might think of as usual military weapons. They used their siege machines to fling diseased corpses or other forms of pestilence over castle walls.
How does a catapult get its energy to launch items?
The catapult works when the potential energy stored in a stretched rubber band is converted to kinetic energy when it snaps back to its loose shape, moving the catapult arm—and the projectile! The kinetic energy of the catapult will give the projectile a force moving up and away from the catapult.
How far did catapults shoot?
Catapults can launch things a fair distance — 500 to 1,000 feet (150 to 300 meters) is common. It is surprising how much energy they can store. The gears are important, because they create a winch. The winch allows a person to put a great deal of energy into the catapult over a period of time.
How did catapults work?
A catapult works because energy can be converted from one type to another and transferred from one object to another. When you let go, this stored energy is released, converted into energy of motion and transferred to the missile (the launched object), which then flies through the air.
What is an example of a catapult?
To catapult is defined as to forcefully throw something. When you forcefully throw your book across the room, this is an example of a time when you catapult the book across the room. A machine that can hurl something a far distance with great force is an example of a catapult.
Are Ballistas still used today?
Ballistae in the Roman Empire Accounts by the finders, including technical manuals and journals, are used today by archaeologists to reconstruct these weapons. After Julius Caesar, the ballista was a permanent fixture in the Roman army and, over time, modifications and improvements were made by successive engineers.
What are 5 types of catapults?
The main types of catapults used were the trebuchet, mangonel, onager, and ballista.
Did castles have catapults?
Castles in medieval times had a lot of things to protect them — high walls, moats with drawbridges, and lots of knights. They took a very basic idea — let’s throw stuff at the castle — and invented very effective ways to do it using an invention called the catapult (meaning “war machine for throwing” in Latin).

What is the spoon on a catapult called!?
The stack of craft sticks on one end of the catapult is called a fulcrum, while the spoon and the craft stick it’s attached to make up the lever arm. When the spoon is pulled back, it has potential (stored) energy.
