I have a question that might be stupid because I'm a brainlet engineering student, but why are there so many seemingly arbitrary types of energy? Why not just only have 4 types of energy related to the 4 fundamental forces? I keep doing these example problems that involve the "potential energy" stored in springs and elastic bands and whatnot, but isn't the "potential energy" actually still kinetic energy, just "stored" as thermal energy, so the kinetic energy of the particles?
And even when you get into weirder things like the potential energy from lifting things up high, isn't that still just the gravitational force? I really don't get why terms like sensible, latent, and potential energy exist. It seems like all you'd really ever need to fully describe the energy in a system is electromagnetic energy, gravitational energy, strong nuclear energy and weak nuclear energy. Is there ever a time where that isn't the case?
Again, sorry if this is a dumb question.
