Energy isn't conserved in a process where there's a trade between
mass and energy according to E = m c2 .
When both mass and energy are tallied, the total is conserved.
The law of conservation of energy itself is not strictly correct since nuclear reactions change a small amount of matter into energy, if this is what you mean.
The Conservation of Matter and the Conservation of Momentum are the consequence of the Conservation of Energy.
The law of conservation of matter states that matter cannot be created or destroyed. Although it can change states and different elements can be molecularly combined to make totally different compounds, the total mass in equals the total mass out. The law of conservation of energy states that energy cannot be created or destroyed; it can only be converted from one type to another. Both conservation laws have the exception that mass can be converted to energy and vice versa according to the equation E=mc2, where E is energy, m is matter, and c is the speed of light.
I am not sure how much of a proof this is; but light energy is involved both in conservation of energy, and in conservation of momentum. A photon has both energy and momentum.I am not sure how much of a proof this is; but light energy is involved both in conservation of energy, and in conservation of momentum.

Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.

There are no "laws" of conservation of energy, just the law of conservation of energy. The existence of friction doesn't change anything - the law of conservation of energy still holds.
Perhaps you mean "energy conservation", or equivalently, "conservation of energy". That refers to the fact that there is a quantity called energy, which can't be increased or decreased (in a closed system).
Yes, you can't make mass appear where none was before. No exception has been found so far. In the Special Theory of Relativity, mass will increase with speed; but this is equivalent to the increase in kinetic energy, and if an object gains energy, another object will lose energy (and therefore mass). So, the conservation of mass (and of energy) is still true.
Portland Energy Conservation's population is 331.
Association for the Conservation of Energy was created in 1981.
Quite simply, that would violate the law of conservation of energy - a.k.a. the First Law of Thermodynamics. No exception has been found so far for this law. This would be like trying to get something out of nothing; the total amount of energy has been found to be constant - no exceptions.Quite simply, that would violate the law of conservation of energy - a.k.a. the First Law of Thermodynamics.
