This is a conceptual question I've been thinking about dealing with conservation of energy.
For example, say you have two charged spheres, one positive and one negative. The positive one is glued in place while you kick the negative one away. How fast would you have to kick the negative one so that it won't come back?
I'm aware these types of problems are pretty simple. potential + kinetic = 0
What I don't understand is how the final energy of the system is zero. Where'd it go?
EDIT: Is it because the potential energy is negative, so the sum is zero initial energy also? That's a weird concept to me to be honest.
