What is the science behind catapults?

Published: May 9, 2023. Sharing is Caring. A catapult is a lever, a stick or beam propped up by a fulcrum (a pivoting point). A lever will magnify the force you put on it if the fulcrum (the pivoting point) is closer to your force than it is to the load. The catapult magnifies your force to throw a pompom in this activity.
