Can a particle have no energy?

Question

Does anything (object, particle, etc) not contain energy? Some particles are said to be massless so can the opposite be true? Are some particles energyless?

Answer 1

No. The minimum energy of a particle of mass m is mc^2. A massless particle like a photon can have an arbitrarily small energy, corresponding to an arbitrarily long wavelength, but it can't be exactly zero.

Answer 2

If a particle has mass it has energy: E = MC^2
where E is the energy in joules, M is the mass in kilograms, and C is the velocity of light in meters per second.

Ergo, there are no energyless particles with mass, although there are massless particles with energy (photons for example).

Answer 3

No, it is impossible since having no energy the particle would have to at absolute zero, which is impossible.

Answer 4

rather the actual Universe exist as a mass this is interior certainly one of those area shape and atomic shape. while a mass is in action it incredibly is declared to be dealing with a technique referred to as skill. The equation E=mc^2 skill that a mass is shifting on the fee of sunshine. If m=0 the equation of skill may be E= 0 x C^2 . So the place there is mass in action there is often skill inflicting its action.

Answer 5

Wouldn't the material density of a black hole have no energy or radiation emission, because it absorbs all energy? In this case, only on a theoretical level, it would possibly be true.

Answer 6

No. If a particle did not have energy, it would not interact with it's environment, therefore it would not be there.

Answer 7

Only if the temperature is at or below absolute zero.
