If you keep on adding more rubber bands in the hope of an ever-increasing force, you will find that the strength of your frame becomes the limiting factor. We collected 374 of the best free online physics games. But the rubber band will then exert a stronger force on the catapult arm and the ball, causing it to accelerate more, shooting the ball further. Hooke’s Law tells us that if we increase the spring constant (by using a thicker rubber band or adding more thinner rubber bands), we will have to use a stronger force to stretch the rubber band when we pull back the catapult. The force that the stretched elastic band exerts on the wooden catapult arm causes it to accelerate and that accelerates the ball too.

Some of it ends up in the thermal store of the surroundings. But not all of the energy from the rubber band’s elastic store has been transferred to the kinetic store of the ball.

Īt the end of the process, the kinetic store of the ball is full and the elastic store of the rubber band is empty. Launch crumpled paper, tiny wood scraps, or pom-poms With practice, become a mini wooden catapult expert and impress your friends with your siege skills. Learn about physics with this easy-to-assemble laser cut wooden catapult kit. Learn about the history of the catapult and trebuchet.Įxplore teeter-totters and other levers in your neighbourhood.īuild a giant catapult outdoors and launch water balloons or pumpkins.At the start, the elastic store of the rubber band is full and the kinetic stores of the catapult arm and the ball are empty. Wooden catapults have been used since ancient times. Have children design and decorate their own catapult. Add boxes or buckets to aim for.Ĭompetition – who can make their pompom travel the furthest? Theme the target zones, such as water with alligators or castles with guards. Hint: Set up the catapult with the fulcrum positioned so that it is least efficient at the start of the exploration to encourage children to adjust it. Which catapult flings the pompom farther?įor older children, challenge them to adjust the location of the fulcrum themselves and see how it affects the distance the load travels.

push gently to move the load a short distance, push hard for a longer distance.įor younger children, set up the fulcrums of several catapults, each in a different position.

Demonstrate how to load and launch the catapults. The catapult is a great way to talk about trajectory and projectiles with kids.It should be pretty easy to calculate the speed an object would be. Objective: Your task is to design and construct a catapult (from scratch) that will fling a ball over a wall and hit. The high accelerations will break most physics engine,s so you may never be able to get good results. You should consider if you really need to simulate the catapult. You could approximate this with a linear spring though. Create “target zones” on the ground or a table using chalk or tape, based on your catapult’s range. A catapult is just an arm attached to a torsion spring.Assemble the catapults ahead of time for younger students.Where should the pivot point (fulcrum) be positioned to make the pompom travel the shortest distance? How can you change the distance the pompom travels? spool of thread or fat marker)Ĭan you get your pompom to the target/across the "water"? wooden ruler or jumbo popsicle stick)Ī round fulcrum (e.g. Also it works on energy storage mechanisms (nothing but the stored potential energy and energy in motion kinetic energy) says that a catapult works on physics. The main types of catapults used were the trebuchet, mangonel, and ballista. Use ramps, pulleys, levers and pendulums.Ī lever arm (e.g. A catapult actually works on the three main terms of physics i.e.
