Mechanics—Motion, continued
Trebuchet—Flinn STEM
Design Challenge™
By: The Flinn Staff
Students make use of an easily adjustable base to test how different heights, arm lengths,
counterweights and release angles determine the flight distance of the projectile.
Catalog No. Description Price/Each
AP8347 Trebuchet—Flinn STEM Design Challenge™ $156.00
Catapult
Where a trebuchet uses gravity and counterweights to provide propulsion, a traditional
catapult uses the mechanical advantage of a lever and tension forces.

Trebuchet
Explore first-class levers, conservation of energy, torque, gravitational force, and
projectile motion. Students will soon learn how the relatively small motion of the counterpoise
weight and the whipping action of the sling launch projectiles so efficiently.

Build a Model Catapult—
Flinn STEM Design Challenge™
By: The Flinn Staff
Build a basic catapult using simple materials. Test the machines to determine how variables,
such as the length of the lever arm and mass of the projectile, affect launch distance.
