Catapult -basics

The mangonel stores its potential energy in

• The Projectile

• The Torsion and Tension of the Rope

• The Type of Wood used to Build the Catapult

• The Size of the Catapult

Mangonel's were a medieval weapon designed to

• Move around on wheels

• Launch projectiles in a parabola arc over walls

• Use gravity to launch the projectile

• Launch projectile low and fast to bring down walls

Tension stores potential energy by

• Being in a state of stretch ready to release

• Being in a twisted state ready to release

• Humans stretching elastic bands

• Using gravity to bring projectiles back to earth

The optimal angle to release a projectile from a catapult for distance would be

• 25º

• 35º

• 45º

• 55º

The elastic bands used in our model catapults will store energy as

• Kinetic energy

• Gravitational Potential energy

• Chemical energy

• Elastic Potential energy

Gravity isn't the only effect on the path of the projectile, there is also

• Air pressure

• Weight of the Projectile

• None of these options

• Air pressure and Weight of Projectile

The potential energy in the elastic bands of model Mangonel's will be converted to:

• Just kinetic energy

• Just sound energy

• Just heat energy from friction

• All of these types of energy at the same time

Energy in an object is destroyed when used?

• False

• True

• Depends
