Catapult Mechanics and Functions

The video tutorial introduces catapults, explaining their historical and modern uses. It guides viewers through building a simple catapult using Kiwi planks, a rubber band, and a coin. The tutorial covers the physics of catapults, focusing on levers, fulcrums, gravity, and inertia. It encourages experimentation with force to observe changes in projectile distance and speed. The video concludes with suggestions for modifying the catapult and invites viewers to explore further.

What is a catapult primarily used for in modern times?

• Building bridges

• Navigating ships

• Digging tunnels

• Launching airplanes from aircraft carriers

What historical purpose did catapults serve?

• Building structures

• Transportation

• Battles and wars

• Farming

Which of the following is NOT a material needed to build a simple catapult?

• Kiba planks

• Rubber band

• String

• Coin

What is the first step in setting up a simple catapult?

• Testing the launch

• Aligning the planks

• Attaching the rubber band

• Placing the coin

In a catapult, what is the role of the fulcrum?

• To provide weight

• To act as a pivot point

• To stabilize the base

• To launch the projectile

What happens to the fulcrum when the lever is pressed down?

• It collapses

• It rotates

• It remains stationary

• It moves with the lever

What two forces influence the motion of a projectile launched from a catapult?

• Pressure and buoyancy

• Gravity and inertia

• Magnetism and electricity

• Friction and tension

Which motion is responsible for pulling the projectile back to Earth?

• Inertia

• Gravity

• Momentum

• Friction

How does increasing the force applied to a catapult affect the projectile?

• It changes the projectile's shape

• It decreases the speed

• It increases the distance and speed

• It makes the projectile heavier

What can be adjusted to potentially increase the distance a catapult launches a projectile?

• The color of the planks

• The type of projectile

• The location of the fulcrum

• The length of the rubber band
