A catapult is a device which is used to hurl projectiles over great distances. The entire catapulting process depends on the storing of potential energy as tension (of ropes or wooden arm) or gravitational potential energy.
This DIY kit shows the basic working principle of a catapult.

Learning Outcomes

  1. A fun way of learning about the characteristics of stored potential energy
  2. You get to see the energy conversion from one form to another.
  3. Correlation between theory and practical becomes easier
