Overview This project will go through a series of steps, converting various types of energy forms to result in a final action

Purpose This project will go through a process of steps and in the end shoot a gun at the desired target (a.k.a. Betsy)

Materials cardboard, pens, marbles, string, wood, billiard ball, dart gun, picture of Betsy, cup, funnel, and various adhesive materials

The very beginning of amasterpiece Construction

Adding the final touches…

Process Step 1: A marble drops down a funnel converting potential energy (mgh)  kinetic energy (½ mv 2 )

Step 2: Rolls down two ramps- again converting PE to KE- then is caught in a cup which pulls up a gate, releasing a billiard ball, producing work (F*d)

Step 3: The billiard ball falls into a cup which pulls down on a string looped over a pulley (F*d), which pulls the spring released trigger (½ kx 2 )

Conclusion Mission Accomplished! Through many trials and changes of product and goal we were finally able to come up with a project that conserves energy and works. YAY!

THE END Thanks to Paul for his overtime work! Disclaimer: He’s our eye-witness. We swear it works!
