Rube Goldberg Machine
The theme for our Rube Goldberg project was Australia and we tried to base our project of that theme. These are the calculations for the protect
This project has 6 main components. The first one is a zip line made of fishing wire on which a weight slides. The second component is the energy transfer from the weight to the ball that it hits allowing the ball to roll into the spiral. The spiral is our third component the spiral allows the ball to descend to the next level while gaining speed. This leads to our fourth component the ball coming out of the spiral hits a different ball transferring the energy. The fifth component Is the ball hitting a weight which triggers a lever allowing the wait to pass and hit another marble. This third marble moves a dowel allowing the spring-loaded knife to cut a rope. The last components is the weight falling because the rope was cut making the pulley release miniature alligator under the cage.
Many physics and engineering concepts were used to create this project these are their descriptions and meanings
Screw: a spiral downward slope that causes acceleration.
Incline Plane: it aids the acceleration and deceleration of an object by having one end higher than the other.
Pulley: used to lift heavy loads without using too much effort.
Lever: a simple machine consisting of a beam and fulcrum, it is able to rotate on a point on itself.
Wedge: it is used to separate to objects or to hold them into place.
Velocity: The speed of a moving object in a certain direction.
Acceleration: The speed of an object with the changes of velocity.
Mechanical Advantage: how many times easier a machine is to use.
Momentum: How hard it is to stop a moving object.
Force: when an object changes its position because of an other force.
Potential Energy: The amount of kinetic energy an object has stored.

Reflection, I believe that the project went well but could have gone better. Some of the problems were communication related if we had talked about what we were going to do more I believe that many things would have gone smoother. I also believe that there were too many people trying to lead I admit I was one of those people and could have deferred to others more often. One of the things that did not go well was the lever we were unable to come up with a solution to its unreliability. Some of the things I learned were communication skills and management skills.
