Wait for some time until the glue dries.

Rubber band catapult designs. This popsicle stick catapult design is an awesome. A simple example is the design of a. To do this you need a hot glue gun and a cap from a water bottle or sports drink bottle. When it is released it snaps back kinetic energy and its potential energy returns to zero.

12 dowel rods i used pre cut 12 and 3 8 diameter dowel rods that i found at hobby lobby. Building a catapult design your way middle school curriculum mechanical engineering 236 potential energy is stored in the rubber band. In this session you will learn how to make a catapult at home.

When the tension is released by releasing the stretched rubber band the arm springs forward the energy is transformed from potential to kinetic and is then abruptly stopped by the stop block. When a rubber band is stretched its potential energy increases. Engineers must understand both potential and kinetic energy.
