Well, it does seem like a "made up", not directly measurable variable. We just have it for convenience of understanding the world. Or am I missing something?

- _hcuq 4y agoMy current thinking (I’m a total dilettante….) is that energy is a state in closed system. The system of course designed by the observer. For example, a cart half way up a hill. Does it have positive or negative potential energy? Depends on how you define your system.
- lisper 4y agoNothing is "directly measurable". Everything in science is a story that we make up to explain our personal experience, including "measurement" and "observation".
- alok-g 4y agoAccording to Noether's theorem, law of conservation of energy is same as symmetry of laws (equations) of physics with respect to time.
