Items used for the device (2) 37” pieces of wood (2) 13” pieces of wood (3) pulleys 50” inches of rope (2) 24” inches of fishing line duck tape and nails Rocks for the counter weight

The Energy used in this device Our box (counter weight) acts as PE. As the box counters the one kilogram weight, it moves the object; therefore, the potential energy turns into kinetic energy. The E-loss is due to the duct tape, fishing lines, and the metal bar when in motion.

Issues At first, we could not get the design to overcome its static friction. It was difficult to accumulate the amount of weight needed to get the device in motion. Amount of Kinetic Friction to slow it down.

Conclusion The design was inexpensive. We learned that friction can be a pain to overcome and account for. Overall, it was a fun project for teamwork and reasoning. We figured out how to counter our flaws within in the device by adding more items for an increase of Kinetic Energy and taking out some items to overcome static friction.
