The measure of motion contained in a body.

>>10477791
But how do photons have it? They're massless.

>>10477822
Motion≠mass , in case normal matter the mass draggs down the speed (from Newton's 2nd law) and in photon mass doesn't so they have maximum motion.

>>10477759
It’s the amount of force it would take to stop something and move it at an equivalent speed in the opposite direction in one unit of time

Something like that.

Excuse me wtf.
How can an object both be moving AND staying at rest AT THE SAME TIME?? Damn, universe, you scarey.

>>10477759
>what is momentum?
Baby don't hurt me...

>>10478065
Relativity, my friend.
You right now are not moving, you are probably sitting at your desk being a huge faggot browsing 4channel, from your point of view you might as well be at rest and the stars on the sky are moving, everything is moving except you. But everything else would observe themselves as being at rest while you are moving. There is no objectivity here, there is no absolute definition on who is actually moving and who is not, since it always depends on who is the one observing.
You are at rest but at the same time you are moving (when observed by something else)

>>10477822
Photons aren't objects floating through space like a football, they are waves (particles) floating through the electromagnetic field
[math]E = \gamma mc^2[/math]
[math]\gamma = 1/\sqrt{1 - v^2/c^2}[/math]
[math]v = c[/math]
having infinite energy and 0 mass makes them move at lightspeed

Does a single particle experience innertia?

>>10477759
>Unironically what is momentum?
Momentum is the increment of inertia.

Traveling through space creates an inductive current of gravitational waves.

Check out this loser.

>>10477759
Anyone who answers with a formula instead of just saying it's a symmetry of space is an idiot.
If a particle is moving in a particular direction, the only way you can distinguish that it is in fact moving is if space is in some way special in one particular direction or axis or whatever. This gives you a momentum.

>>10479877
This
Think of force in this way. If you push on an object, an equivalent way to think of that is to think of you breaking the symmetry of space and providing the object with a special direction, so that it can distinguish one way from the other along that axis. Equivalently, you've given it momentum along that axis in the direction you're pushing.
If people don't know this and reach for fancy terminology or a formula then you should relearn your basics.

Light is the lightest possible mass. If there was something lighter, it would be faster than light.

>>10479877
Literally what >>10477766 said, except they have more rigorous mathematics behind their statement

>>10480279
If you need rigour to hide your lack of ability in explaining the physics then sure

>>10477895
Not an argument

>>10479877
>the only way you can distinguish that it is in fact moving
stopped reading there

>>10477759
Momentum is force multiplied by seconds, in other words, >>10477842 is right

did you have a stroke anon? cause your post almost made me get one

>>10477790
ermm

where did you get this, do you have a daughter and can I marry her if I get a job working for you in the nearby future? DONT LIE

I wanna add one now


Momentum has the force to contain that you are not "allowed" the movement that in the mind you contained a shallow example for as the only excuse you can arrange a medium as a function for.

That's momentum.

You guys have spheres and cubes and even a planet here I think. But no momentum. Look at me.

>>10478230
>infinite energy

what?

>>10480276
subatomic particles with negative mass don't move faster than light

>>10482147
Negative mass? Since when

>>10482171
In Hawking radiation, the virtual particle falling in to the black hole is said to somehow have negative mass, making the BH lighter.

>>10478230
Youre a dangerous person my friend. It's incredulous

idk what that even means but that math is weird for the explanation

>>10481901
That's pretty much exactly right though

>>10482416

>>10477777
just fuck his conservation up senpai

yes.

IT'S QUANTIZED INERTIA!!!!!!!!!!!!

THERE IS A MOMENTUM PARTICLE!!!!!!!!!!!

or at least no just yet
please stop with this meme

>>10483030
You pretty much negotiated it yourself.

>>10482920
nope

you can’t distinguish something is moving u less it’s accelerating

fucking trannies, keep politics out of the physical sciences

>photon
>E=γmc2
hell no, E=pc = h/wavelength

>>10485382
You can determine it's moving relative to other things which is the relevant point here and which is what momentum does

>>10485466
* = hc/ wavelength
p = h/ wavelength
