Rube Goldberg Machine
A Rube Goldberg Machine is a machine that makes something so simple become complicated. The machine needed to have 5 simple machines, 10 steps and 4 energy transfers. For our 5 simple machines we used a a wedge, an inclined plane, a screw, a pulley, and lastly a lever. The machine we created had an end result of a piece of bread falling into a toaster. With us spending 3-4 weeks on this machine we collaborate as a group and we made a wonderful machine called " Breakfast Paradise".
Physics Concepts:
Force: Force is a push or pull on an object. It can be calculated by using mass x acceleration. We found force on wedge.
Mechanical Advantage: Mechanical advantage is how much easier you make a tool. In our project we found the mechanical advantage for the first ramp and the lever.
Velocity: Velocity is the rate of distance covered in a distance. For the velocity, we found it for the speed of the ball in the tube.
Acceleration : Acceleration is the rate of change of velocity speeding up or slowing down. We found the acceleration for the ball on screw and for the second ramp.
Potential energy: For potential energy we found the potential energy of the tennis ball.

Steps used in the project;
Step 1. Pull wedge out of ramp
Step 2. Ball rolls down the ramp
Step 3. Ball rolls down screw
Step 4. Ball rolls down the second ramp
Step 5. Ball hits tennis ball and fall into a cup
Step 6. Cup drops and other cup hits the lever
Step 7. The lever drops another ball
Step 8. Ball goes into funnel through the tube
Step 9. Ball rolls down third ramp
Step 10 . Ball hits tennis ball and the tennis ball falls off the table and pulls down the piece of cardboard
Step 11. Toast falls into "toaster"

Reflection:
In our project we had a lot of ups and downs. The screw was one of the hardest things to make because we had to make it from scratch. First, we got two CD's and cut them to the middle and tried to bend them correctly in order for the ball to roll on the screw. After that we saw that there was a crack in the CD and had to start over. The second time we tried, we did everything the same and attached it to the board. Once we attached it we turned around for a second and the whole board fell and the screw scattered. Lastly, we built the screw for the last time and this time it was the best screw we every made. I guess when people say third time the charm it's true. One thing I learned about myself while doing this project is that I need to take control sometimes. During the group project I've noticed that I always take a step back. Now I need to take the lead.
I worked on this project with Josh Franks, Matt Cassidy, and Nick Brandis.
