Slingshots and Catapults

Demonstrate projectile motion, exertion, force, velocity, potential / kinetic energy, and angles with slingshots and catapults! How much force is needed to project objects of different weights? What angle will fly your object the farthest? 

As a class, or an individual homework project, have kids design a catapult or slingshot. Experiment using different amounts of force. What angle creates the best launch? Try launching objects of different weights. Did heavier objects need more force and require more energy? Measure the distance of the objects you launch!
