 A pendulum swings and hits the marble  The marble coasts on a curved path until it collides with a domino.  The domino then falls into the cup on a pulley system.  As the green cup is forced down, the purple cup tilts up, knocking the weight out in a linear path to turn on our push lamp.

 Torque: observed at the start of the device.  Conservation of Energy: applied throughout the travel on the pathway.  Center of Mass: can be calculated in our purple cup as it balances the weight.  Conservation of Linear Momentum: shown when the marble hits the domino and also when the weight hits the touch lamp.

 Our sketched designs did not attack approaches accurately nor realistically.  The materials we had on hand were not very sturdy.  We had to do a lot of adjusting and rearranging to have our weight hit on center perfectly.  All were unfamiliar with using power tools.  The pulley system would not allow the weight and cups to rotate properly.

Our team project gave us all a better insight on the material we learned this semester in EF 151. By doing the hands on application, it provided us with a better foundation of how to understand and apply these fundamentals. All can agree that this project was entertaining
