You scratch my back, I scratch yours. Gender equality. All Lives Matter. Bringing balance to the force. What goes around comes around.
1st Law of Thermodynamics:
Some conservation of energy examples:
Another example is dropping a rocket from high altitude to sea level. If you watched space documentaries, space shuttles heat up upon reentry. In a perfect vacuum, we'd expect all the gravitational potential energy to change into purely kinetic energy, the energy of motion. In the atmosphere, we have air resistance. The kinetic energy is not as much as we'd expect. If I had
Purely on theoretical physics and mathematics;
According to Noether's theorem , laws of physics are unchanging with time hence energy being the conjugate pair of time is conserved.
