I'm not quite sure I'm understanding potential energy correctly. Let's say we have a runaway planet in deep space which is going in a perfectly straight line. The planet is perfectly spherical and doesn't have an atmosphere. If an object on the surface spontaneously (for the sake of simplicity...

Thanks again everyone, guess I'll have to get some math books now :)

I'm terrible with math too, unfortunately. Another one of my goals is to fix that. I'm serious enough about learning more in physics, but not for purely serious purposes. In what areas would it become vital for me to know calculus? I'm a bit reluctant to learn calculus, but if it's really...

Thanks Robert. What textbooks would you recommend though? I need some books that discuss things like the structure of the atom and electromagnetism. And thanks for answering my questions vanesch, but I still don't really understand, would a negative ion lose it's electron if it were in...

Hiya. I've gotten behind in physics lately. Disturbingly so, in fact. I just can't stand how little I know, so I've recently undertaken the task of educating myself using Wikipedia, but it's terribly hard. I may have misinterpreted some things, and some things don't make much sense at all, so...
