Just press the green flag a couple of times to start and ensure that the program runs smoothly.
These notes are mainly for clarification for my science teacher. The red arrows are energy transfers while the blue arrows are energy conversions. The transfers happen when an object hits another object and transfers its KE to the next object. The conversions happen when the PE of an object is converted to KE, causing it to move. For more in-depth descriptions of each transfer and conversion, please take a look at the Energy Device Review sheet. The graphs in the first portion show how the ball converts its PE into KE, having the relative amount of PE go down as its KE goes up. The second portion's graph show each of the dominoes have energy as they fall down and transfer their energy to the next as the fall down. The last portion shows both cups' energy levels. As they sit still, they still have PE. Once they move, their PE begins to convert into KE. After they finish moving, they no longer have any energy, which would have been transferred to the next item in my energy device.
