The Rube Goldberg begins with an iPhone 6 vibrating into a domino, which then hits two other dominoes and eventually knock the marble down a ramp. At the bottom of the ramp is three other dominoes waiting to be hit so that they can drop a marble down into another ramp, which leads into a funnel. At the bottom of the funnel is a platform that brings the marble into a blue tube and then at the end of the tube is a car. The car then gets hit by the marble and then rolls down a ramp into a bell.
In my Rube Goldberg project the energy transfers are potential energy, kinetic energy. I used potential energy in many parts of my project starting with a marble that is waiting on the edge of a platform and kinetic energy would be the speed of the marble while it’s traveling through my project.
