![]() Its motion can be analyzed in two dimensions – horizontal (x-axis) and vertical (y-axis). Projectile motion: The launched object follows a curved path, known as projectile motion, due to the influence of gravity.In this case, the elastic band stores the energy as it’s stretched. Elastic potential energy: This type of potential energy is stored in elastic materials when they are stretched or compressed.The greater the force exerted on the object, the higher and farther it will travel. Force: The catapult’s force is what causes the object to launch into the air.There are a few key concepts at play in the popsicle stick catapult: The conversion occurs because the elastic band, which was under tension, returns to its relaxed state, propelling the object into the air. Once you release the catapult, the potential energy converts into kinetic energy, which is the energy of motion that an object possesses. Potential energy is the energy an object possesses because of its position, in this case, the stretched elastic band connected to the popsicle sticks. Let ‘er rip! The Science Behind CatapultsĪ catapult stores energy when you pull it back, creating potential energy in the process. Kids of all ages will have a blast testing out their catapults to see how far various objects can fly, while also gaining a hands-on understanding of the science behind it. I love how this simple arrangement (using everyday objects) allows you to transform the potential energy stored in the bent sticks into kinetic energy, to send projectiles flying. Today, you can create a simple and fun popsicle stick catapult at home to learn about the basic principles of physics by making a lever and fulcrum to launch objects in the air. This simple machine was first used as a powerful war machine to hurl stones, projectiles, and other objects at enemy fortifications. What are catapults?Ĭatapults have a rich history, dating back to at least the 1600s. Whether you’re a teacher looking for an interactive classroom activity or a parent seeking a new project to keep the little ones entertained at home, popsicle stick catapults won’t disappoint. I love creating STEM (or STEAM, if you want to include art projects) activities for my kids and have shared several simple science experiments on this site, including: ![]() It does not store any personal data.Busy bodies need activities to keep their hands moving and their brains engaged! With 3 busy boys at home, I know firsthand just how important it is to keep kids entertained AND learning.Īnd STEM activities are the perfect way to “kill two birds with one stone” and accomplish both tasks at once!
