2. The Design A two ball machine
One ball hits a lever that initiates a second ball.
cardboard, duct tape, styrofoam, pvc, duct, hot glue

3. Stored Energy Potential gravitational energy (mgh) at all levels
Push by lever causes Work In

4. Construction Issues Used weak tape in the beginning- hot glue
Getting the right slope
Reducing friction
Increasing friction

5. Conclusion It took long hours!
Adjusting the slopes lessens time on coaster
Adding different materials can decrease or increase friction
Ultimately, the coaster works
