is light an example of perpetual motion?

Answer 1

An object moving inertially (ie with no net acceleration) will continue to move inertially. In a sense this is "perpetual motion", however it isn't free energy. This is because it doesn't cost energy to maintain inertial motion.

Answer 2

Duality lets you treat a photon as either a wave or a particle. And either way, it's perfectly legitimate to call it motion.

That being said, the phrase "perpetual motion" is traditionally used in the context of a "perpetual motion machine", that is, a machine that can run forever, and generate free power. Light would not be an example of this kind of perpetual motion, because you can only harvest the energy by absorbing (and therefore stopping) the photon.

Answer 3

No

Perpetual motion is anything which creates as much energy as it exerts, or produces more energy than it exerts

The term perpetual means continually, or a constant. while light will travel through deep space for what may seem like a very long time, it is absorbed into particle mass once it makes contact, unless it is reflected, or refracted, but it is not perpetual

If light were perpetual than we could simply trap a beam of laser light between mirrors, and it would function forever after leaving the source.

Answer 4

Not sure about that but air is an example of perpetual motion.

Answer 5

Light as in sun light, or electricity light? How is light a form of motion?

Answer 6

If light is energy, ( as in a particle) and energy can not be destroyed or created, than light is. If light is a wave, and waves can have distructive interference,than light is not. Remember, light has dual nature.

Answer 7

The earth is genuinely slowing down in this is action very slowly. the in straight forward words reason it strikes for this kind of huge volume of years is that there is amazingly little friction in area. even as scientists say that you won't be able to create perpetual action, it excludes that in a vacuum, and the gap round earth is on the point of being a vacuum. there continues to be a lot of gas and stuff up there notwithstanding so it slows down, notwithstanding the quantity of kinetic potential it had to commence with became enourmous, and the friction is small, so it may proceed for billions of years or notwithstanding lengthy. they have despatched unmanned spacecraft up that proceed on ad infinitum besides, those are even extra out and performance a lot less friction upon them (the gas is way less dense extra out), so even notwithstanding they'd a lot less kinetic potential to commence with, the smaller floor section and a lot less friction skill they could proceed likely until eventually Jesus returns and all of it receives said as to an end. the conception of a perpetual action gadget in the international continues to be no longer accessible. inspite of if a vacuum is created, it also desires to be countless, or the item will purely collide with the walls, and there desires to be a lack of gravity, or the item will purely lie on the bottom besides. As for the tide, this comes from the action of the moon; this is gravitational pull attracts the waters up even as it comes close to them, then they recede even as it strikes away. The moon even were given its potential billions of years in the past, and could be slowing down besides. i purely wasted my time being nerdy over an unserious question yeah? EDIT: end coming up with comebacks hostile to human beings, you requested the question, evaluate the solutions with out arguing all of them. the great contributor guy that feels like a heavy-metallic fan who wrote hundreds became exciting

Answer 8

I don't recall light having any measurable particles, so what would be moving?

Answer 9

Al: Nuttin can't do Nuttin.

Answer 10

yes, and at great velocity
