# Which force is used to move a catapult?

## How do catapults work?

A catapult uses the sudden release of stored potential energy to propel its payload. Most convert tension or torsion energy that was more slowly and manually built up within the device before release, via springs, bows, twisted rope, elastic, or any of numerous other materials and mechanisms.

## What forces were used to move the projectile pushes or pulls catapult?

Students pull back on the catapult, powering it up. When released, the catapult’s moving arm pushes a projectile, making it move in turn. Gravity and air resistance eventually stop the projectile.

## What law of motion do catapults use?

Catapults are one good way to learn about the relationship between force, mass and acceleration. The relationship F = ma is called Newton’s second law of motion because it is a mathematical description of the relationship among force, mass and acceleration.

## How does a catapult work simple answer?

The catapult you are about to make uses elastic potential energy stored in a wooden stick as you bend it. 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.2016-01-21

## What forces are at work with catapults What makes them work?

For a catapult, potential energy is stored as elastic energy. This energy results from the force put in as the muscu- lar push or pull needed to stretch, bend, or twist some sort of elastic material that is attached to the throwing arm. For a trebuchet, the potential energy is gravitational.

## What forces does a catapult use?

What forces do catapults and trebuchets use? Catapults: Catapults take advantage of elastic force, involving stretched, compressed, bent, or twisted material. To prepare a catapult to launch a rock, it takes work to twist a rope (provide torsion), to stretch a rubber band (provide tension), or bend wood.

## What is a catapult and how does it work?

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. A catapult uses the sudden release of stored potential energy to propel its payload.

## What forces act when a catapult works?

A catapult is a launching device that allows us to experimentally observe projectile motion (see Figure 1). Once the ball is launched, the only forces acting are gravity and air resistance. Gravity accelerates the ball in the negative y direction. Air resistance accelerates the ball in the opposite direction of travel.

## How does a catapult fire?

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 armâ€”and the projectile! After students build their catapults, they will test them by launching projectiles.

## What is a catapult and what does it do?

catapult, mechanism for forcefully propelling stones, spears, or other projectiles, in use mainly as a military weapon since ancient times. The ancient Greeks and Romans used a heavy crossbowlike weapon known as a ballista to shoot arrows and darts as well as stones at enemy soldiers.

## What simple machine is a catapult?

lever simple machine

## How do you explain a catapult to a child?

A catapult is a simple mechanism used to forcefully propel stones, spears, or other projectiles. It has been in use mainly as a military weapon since ancient times. Soldiers would use the catapults in both siege and defense maneuvers to capture or protect cities or castles.

## How is a catapult operated?

Nearly all catapults employed in ancient and medieval artillery operated by a sudden release of tension on bent wooden beams or of torsion in twisted cords of horsehair, gut, sinew, or other fibres. An exception was the medieval trebuchet, powered by gravity.
