Levers are all around us, though rarely recognised or
noticed. A catapult uses a lever system to convert
potential/stored (gravity or elastic) energy into kinetic
(movement) energy, to throw a projectile as far as possible.
This project builds 2 models – a 3rd Class catapult (predesigned)
and a 1st Class catapult – this one you need to
design, make and test. There is plenty of room for
competition with others, to see whose catapult can throw
their “ammo” the furthest.
