What would have happened if energy and mass together were not conserved in this universe?

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.

Is energy always conserved in the universe?
No - However, energy and mass are conserved. This is dictated by Einstein's most famous equation: ∆E=∆mc2
Is energy is conserved when an atom emits a photon of light?
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.
Are matter and energy together are always conserved true or false?
True
What happened to amplitude when wave reflected?
Energy is conserved with an idea reflector, so there is no change in amplitude.
Is mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved

Does a rollercoaster obey the law of conservation of energy?
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".

True

Energy is conserved with an idea reflector, so there is no change in amplitude.
Does E equals MC squared suggest that mass and energy together are conserved?
yes
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.
Mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved

In a collision what is conserved?
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.
How is energy conserved in transformation?
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
