My machines had Potential energy , kinetic energy and chemical energy. Potential energy was used at the top of the inclined plane. Kinetic was used when the ball was going down the ramps and when the weight dropped from the pulley. and chemical energy was used when the candle burned the rope to make the weight fall to hit the orange. There was no assistance from my hand after the machine started.
The simple machine has ten steps to preform the task plus one another step. All the simple machines use din my project are all labeled correctly the way they work and what they do. The whole Rube Goldberg worked and completed the task it was supposed to complete which was to squish an orange. The weight did sometimes bounce off the orange and fly out of the funnel and the orange would also sometimes fly out. Then it finally worked and it squished some of the orange juice out into the cup.
