Rube Goldberg Machine
Our Rube Goldberg Machine works by sending a marble down a tubing screw. It then falls onto an inclined plane, then rolls down into a cup. This cup is attached to a pulley. At the other end of the pulley is a wedge. As the pulley lifts the wedge up, a toy car rolls down an inclined plane. Then, the car hits a tennis ball, which falls into a cup. The cup is connected to a lever and pulley system, which ultimately leads to dropping two marbles down a tube. They roll through, then hit another toy car with a stylus attached to it. It then takes a picture on an iPad.
Note- Our calculations are in the presentation.
I think we did well on this project. One thing specifically is that we came up with a lot of ideas for steps. We had trouble choosing our favorites. Another thing that went well is that we came up with effective ways to build things so they worked more often. Almost everything was working 100% of the time. The one step that had trouble was the car onto the iPad, because we had to align it perfectly for it to work. Another thing we could have worked on was time management. We messed around a lot during the beginning and ended up learning that it's better to get it done before, then have fun later.
Concepts
Force- a push or pull upon an object, and causes a change in motion
Time- progression of events
Distance- the amount of space between two points
Velocity- rate of distance covered in a direction
Acceleration- rate if change of velocity
Mass- amount of matter in an object
Work- amount of energy out into something
Potential Energy- energy an object has due to its height
Kinetic Energy- energy due to motion
Mechanical Advantage- how much easier a tool mkes something
