By How does a catapult work?
A catapult works because energy can be converted from one type to another and transferred from one object to another. When you let go, this stored energy is released, converted into energy of motion and transferred to the missile (the launched object), which then flies through the air.
How does a catapult work Physics for kids?
The catapult science basically involves some physics and engineering skills to hurl a projectile without the use of an explosive. It works mainly by using potential and kinetic energy stored in the rubber bands. Potential energy is the store energy where as the kinetic energy is the energy in motion.
How is a catapult a simple machine?
A catapult is a type of simple machine called a lever. A lever is a bar centered on a turning point called a fulcrum that’s used to raise or move weights. Levers make it easier to lift heavy things, like a person or a seesaw.

Because parachute games encourage cooperative, non-competitive play and reinforce turn-taking and sharing. While most gross motor activities for young children develop muscles in the lower body more than the upper torso, parachutes strengthen primarily shoulder, arm and hand muscles.
