Electricity, Magnetism, and Motion
... Mechanical energy. Electricity produces motion! How can you make a loop of wire continue to spin? Current is reversed just as the loop gets to the vertical position. This reverses the direction of the movement of both sides of the loop. The current reverses after each half turn so the loop spins con ...

... Laws of Thermodynamics 1. Conservation of energy: Energy is neither created nor destroyed; it is transformed. you can't take out of a system more than you put in. you can't win 2. The entropy of the universe is continually increasing. perpetual motion and a heat engine with 100% efficiency are both ...
