No - However, energy and mass are conserved.
This is dictated by Einstein's most famous equation: ∆E=∆mc2
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.
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.
Mechanical energy is not always conserved. It can be converted into other forms of energy, such as heat or sound, through processes like friction or collisions. This means that the total amount of mechanical energy in a system may change over time, making it not always conserved.
Mechanical energy is always conserved in a closed system. It can exist as potential energy (stored energy) and kinetic energy (energy of motion). This conservation principle is known as the law of conservation of mechanical energy.
Mechanical energy is not always conserved. It can be converted into other forms of energy such as heat, sound, or work, due to external forces like friction or air resistance acting on the system. In the absence of non-conservative forces, mechanical energy is conserved according to 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".
No. Total energy is always conserved, but not so mechanical energy.
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.
no it's not cuz if there is friction energy wont be conserved

Energy is always conserved. When friction is present, the energy usually just turns into heat.
There is no such thing - energy is ALWAYS conserved.
Yes, this is a simple physical change and matter is always conserved in these. In fact, matter is always conserved except in nuclear reactions where the sum of matter and energy is conserved.
