What is a Rube Goldberg Machine?

 A Rube Goldberg Machine is a series of events that cause one final action. It is a collection of multiple, simple machines that are used to elaborately complete a simple action.

Velocity-  Rate of distance covered in a direction.  

Acceleration-  Rate of change in velocity

Force- Push or pull on an object causing a change in motion. 

 Work- work of energy put into something. 

Potential Energy- Energy an object has by being at a height or position in a gravitational field. 

Kinetic Energy- Energy due to motion

Mechanical Advantage Real- How much less force is required when using a tool.

Mechanical Advantage Ideal- How much more distance do you have to push when using a tool. 

Simple Machines

In our project, we had a total of 5 simple machines. Our first simple machine is a wedge. At the beginning of our project, we lift up a wedge that makes the ball start rolling. Our second simple machine is an inclined plane. We have 5 incline planes in our project representing famous San Francisco landmarks. The third simple machine is a screw. After the ball rolls down the inclined plane it circles down a round funnel. Fourthly we have a pully. A weighted ball falls into a box that is attached to the pulling lifting up a marble.  The last simple machine we used was a wheel. 

Reflection 

Through this project, I have learned how to be a helpful collaborative teammate. For example, when a team member and I had different ideas about how to approach a challenge, we would come up with an idea that supports both of us. Another skill that this project has taught me, is how to be a critical thinker. When we would test out different methods when approaching a challenge, I learned how to quickly come up with solutions. A challenge that I faced during this project was coming up with ideas, and making my vision come to life. Another challenge I faced was learning how to make each individual step work with each other.
