Proof of conservation of energy? - Physics Stack Exchange
Dec 29, 2020 · In general relativity conservation of energy-momentum is expressed with the aid of a stress-energy-momentum pseudotensor. The theory of general relativity leaves open the question of …
Does Newton's third law violate the law of energy conservation?
Sep 22, 2024 · Energy conservation and linear momentum conservation are two indipendent laws, which need to be verified indipendently. What is true is that the law of action and reaction, i.e. Newton's …
Proof Of Conservation Of Energy - Physics Stack Exchange
Jan 15, 2023 · Note that in the answer, it rests on Newton second law, which means the conservation of energy which is axiomatic in mainstream physics at the mechanics level reverts to Newton's second …
Why is the law of conservation of energy violated here?
Oct 10, 2021 · Such internal energy is hard to keep track of, making the energy conservation law basically impossible to use for simulation, prediction and calculation without much more data. This is …
Why doesn't $E = mc^2$ contradict the conservation of mass principle?
Jun 14, 2017 · E=mc^2 implies that mass and energy are interconvertible. Mass can be converted to energy and vice versa. Therefore, mass is not conserved.
Can energy conservation be derived from Newton's laws?
Jun 22, 2016 · Can the idea of energy conservation be derived from Newtons's laws? From inspection of his laws you can vaguely discern a relationship but I want to know if you can manipulate his laws to …

If conservation of energy was wrong, how would we know about it?
Conservation of energy is a fundamental law of our universe. There are many places where we cannot account every bit of it to check its validity but I guess you are thinking like, how to prove a law by only …
What is the relation between Newton's third law and law of …
Nov 30, 2022 · The internal forces can change the internal energy of a system. The absence of external forces does not grant the conservation of KE but it does so for momentum. So, the third law does not …
