In that case, it is my understanding that the very laws of physics would change over time. For more information, do some reading on Noether's Theorem. It includes some very advanced math, but briefly, every law of conservation is related to a symmetry in nature - and the Law of Conservation of Energy can be derived from the fact that the laws of nature don't change over time.
Energy is always conserved in a closed system, according to the law of conservation of energy. However, in the universe as a whole, energy may not be conserved due to the expansion of space-time, which can lead to a net increase in energy.
If matter, mass, and energy were not conserved, it would violate fundamental laws of physics and lead to unpredictable and chaotic behavior in the universe. This could result in unstable systems, unexpected interactions, and potentially the breakdown of the laws that govern our understanding of the universe.
Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
In an elastic collision, kinetic energy is conserved and the objects bounce off each other without losing energy. In an inelastic collision, kinetic energy is not conserved and some energy is lost as the objects stick together or deform.

When you look closely enough, you find that EVERYTHING does.Better start getting accustomed to this idea - basically, in our Universe, energy is ALWAYS conserved. It really shouldn't be necessary to ask whether energy is conserved in specific cases - the answer will always be "yes".

yes
No. Total energy is always conserved, but not so mechanical energy.
no it's not cuz if there is friction energy wont be conserved

A energy can be changed or transformed. When you rub your hands together,your hands become warm. Mechanical energy due to motion is changed into heat energy
