Matter and energy are always converted due to the theory of relativity.
kinetic energy..........
no it's not cuz if there is friction energy wont be conserved
Basically, in physics, total energy is always conserved. Of course, it is possible for some of the energy from a car to go somewhere else.
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.
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.

No. Total energy is always conserved, but not so mechanical energy.

Energy is always conserved. When friction is present, the energy usually just turns into heat.

No - However, energy and mass are conserved. This is dictated by Einstein's most famous equation: ∆E=∆mc2
There is no such thing - energy is ALWAYS conserved.
Always. No exceptions are known.
