    Understanding Work & Power for Heavy Objects

    Lsos -- I'm sorry, I don't follow either paragraph. Say the heavy object starts at point A. Assume it starts at rest and does not spontaneously disappear from point A and reappear at point B. To get to point B, some force needs to be applied to the object. And if a force is applied over a...

    What Can Induce Electron Flow and Why Are Magnets So Dominant?

    I can think of three ways to induce electrons to flow and generate electricity: 1. Light (i.e. PV cells) 2. Catalyzed chemical reaction (batteries, fuel cells) 3. Magnetic field (turbines -- gas, wind, water, nuclear... everything else I can think of) Mostly turbines. I was wondering if...
