Since we study momentum before energy I've had kids ask me the
question - why isn't energy (particulary kinetic energy) a vector?
It strikes me that this is a great question because it can be
addressed at so many levels. Feynman would no doubt say something
rather different to his colleagues than I would to my weakest 10th
graders and so on. How would you answer this?
