# How do you build a catapult for a physics project?

Simple craft stick catapult:

1. Stack five craft sticks together and wrap a rubber band around each end.
2. Stack two craft sticks and wrap a rubber band around only one end.
3. Slide the five sticks in-between the two sticks, as shown.
4. Wrap a rubber band where the two sections meet to hold the catapult together.

## Similarly, how do you build a catapult that can launch a tennis ball?

Moreover, what are the physics of a catapult? A catapult is a simple machine. As the arm is pressed down in ours, tension builds and energy is stored. When the arm is released, the elastic energy (think slingshot) is converted to kinetic energy — the energy of motion. When an object is placed in the bottle cap, it will move at the same speed as the arm and lid.
