Re: Finding work done by variable force - line integral

How do I tell whether a force is conservative? I think if it's a force field -- meaning it's only dependent on the position -- it should be conservative, correct? A field dependent only on positions isn't neccesarily conservative. The most direct way is to show the curl of the force field is zero e...

Re: Free Energy

You can rest assured that free energy by the definition of "a source of energy that is infinitely available, any time, with no external requirements or fuel" is impossible. Our laws of physics are pretty much built upon that assumption. Energy conservation isn't an assumption; it's a cons...
