If you fire a gun while running, does the bullet come out faster than if you shoot standing still.
>>
>>7926952
these two situations are not comparable if you cannot prove that they are comparable.
>>
>>7926952
ground speed yes
gun speed no
>>
>>7926952
not if you're running at the speed of light.
>>
>>7926952
Yes
>>
>>7926952
In relation to what?
>>
>>7927145
To the guy being shot.
>>
>>7926952
In reference to what exactly? And nice pic btw
>>
>>7927212
--> >>7927176
>>
yes but the final velocity of the bullet relative to the ground is slightly lower than the simple sum of the two velocities
>>
>>7926952
No.
If you run at Y velocity in the positive x direction, and shoot a bullet in the negative x direction at velocity Z, the bullet will travel at Z-Y velocity,
So slower.
>>
>>7927278
But he's firing in the positive x direction. So yes.

AK bullet speed: 715 m/s
Your top speed: 10 m/s

Bullet speed: 725 m/s

I kekd out loud

Kol
>>
>>7927986
I can run like 300 m/s I was the fastest kid in school race me irl if you don't believe me you'll probably chicken out though cuz you're yellow
>>
>>7927950
Not specified
Half of possible directions would increase bullet velocity, half would decrease it

So, the average would mean it has no effect :^)
>>
>>7928544
Next level shitposting
>>
>>7928956
I'm shitposting and running at the same time
>>
>>7926952

The bullet fires because of the compressive force from the gunpowder's ignition
Unless you're moving faster than the bullet, the affect of your movement is next to none
>>
>>7928959
Woked up everyone
>>
>>7930038
>Unless you're moving faster than the bullet, the affect of your movement is next to none

So if you're moving almost as fast as the bullet, it doesn't matter? But if you're moving slightly faster it does?
>>
So what happens if you're moving at bullet speed or faster, and shoot in the same direction? The bullet will come out of the muzzle at bullet speed, therefore would the gun catch up to it instantly after it's fired and explode in your hand?
>>
>>7930264
Of course. Have you never heard of conservation of momentum? It's just like the doppler effect.
>>
>>7930354
vectors add, you melon
>>
>>7926952
The bullet is faster relative to the ground, but not relative to the gun.
>>
>>7930281
No. Relative to the gun, the bullet moves at speed A. Relative to the ground, the gun moves at speed B. Therefore, relative to the ground, the bullet moves at speed A+B.

This is literally PHYS 101.
>>
>>7926952
Of course, consider this situation: You're standing at one end of the train carriage, and you run to the opposite end. Are you running faster? Relative to the train, no you're not, relative to a third observer set outside the train? Absolutely.
>>
>>7930960
And you're moving at speed C relative to the ground, therefore A+B+C

Say it to my face and not online. See what happens.
>>
What if when you are running, the recall causes your hand to move backwards 2x faster than you are running. Then the bullet is slower than if you were just standing still with a more ridgid arm.

Also are we considering what happens if there are wind gusts in the positive and negative x during bullet release?
>>
>>7927986
What kind of AK though?
>>
>>7926952
Better question:

If you shine a flashlight forward while running, do the photons come out faster than if you shine the flashlight standing still?
>>
>>7931955
Yes.
Assuming that you run out of glass into a vacuum, and stand still in the glass.
>>
>>7926990
If you are running a the speed of light, how do you make the next step? Your leg would need to travel faster than the speed of light for it to step in front of you.
>>
>>7931955
nope

light is constant no matter what

that's what the whole time dilation deal comes from
>>
>>7930993
Wut. Isn't C==B?
>>
what if you were running, then threw the gun forward, and shot it forwards

would it go even faster?
>>
>>7932071
Because ur not there to hold the gun the explosion is divided into two so the bullet goes half as fast
>>
>>7931965
Wrong because no matter how fast your running the speed of light is constant so if your leg goes the speed of light it will be faster then you by the speed of light so you can take the next step.
>>
>>7932107
but what if you ran faster to catch up with the gun you just threw

then fired it
>>
>>7932116
Why not just run faster in the first place
>>
>>7926952
No, because the speed of bullet is a fundamental constant that never varies, regardless of the frame of reference you're in.

How far in the spectrum do you have to be to think that was a serious comment?
>>
>>7932121
holding the gun slows you down tho
>>
Shooter's speed = x
Bullet speed = y
Assuming gun travels at same speed as shooter throughout, ie no kickback or hand movement.

From the point of view of the Shooter the bullet travels at y - x because he is moving towards the bullet at speed x.

From the point of view of an observer standing still, the bullet travels at x+y.

Seriously just got leukemia. Its is physically impossible to 'run' anywhere near light speed....Physically speaking that's is.

<(*{[LEGIT] ANSWER}*>.

It moves at the normal speed the bullet speed is and independent variable. It isn't like a slingshot where the cup is the sole source of acceleration. In which the object being shot will travel at the speed of the cup until the cup reaches its length restriction and comebacks back leaving the object with a lot of borrowed momentum. A gun uses the bullet itself to make it accelerate. the ignition of the gun powder causes it to shoot forward and from the time of ignition to explosion. any motion outside of the chamber is 'slowing down' because its happening to fast ~it is proven the faster you get to light speed the slower time gets~ from that to movement that moment its propels itself forward. the instant before it is pushed forward the exact position of the gun is what matters and if you think in a slower time frame the propelling happens instantaneously so movement is irrelevant because it is moving from that exact point at that exact time and to calculate movement speed acceleration there needs to be observation between more that one position. but is is firing from one initial position at the rate of an instant anything slower is not moving at all like quicksilver/the flash (just trying to illustrate my point) when they move at the rate they do everything thing to them is extremely slow almost not moving and they aren't moving at an instantaneous speed yet ...so do the math and infer the rest.

Will that mean the bullet will just fly backwards into your chest?
>>
>>7930970
Completely inaccurate. If a train is moving at what ever speed and you are running on the train and a friend is on the ground watching you. it may seem like you are running faster but if he take you speed at a certain point at matches that speed that friend will be running with you. because that speed is the train speed .. your speed at on A (1, Singular) point is still the speed of the scale of movement variable (the thing you are moving on.)....Technically speed is a relevance topic its a measure of distance over time. you don't count the earth as the distance anymore. its the train . distance on the train over a certain amount of time. which is independent from the speed of the train on the ground

Learn to commas and line breaks.

Situation A: you're running on the still ground

Situation B: you're running on a moving train

In which situation is your net speed fastest?
>>
>>7933023
Not into your chest but it will just stop after it left the gun.

No movement: everything is faster than you *default relation*

Movement: are faster than materials not moving

Increased speed: Faster than things around you

Closer to light: Time slows down

Light speed: times stops


(this one is only a theory) Faster than light: time goes backwards

Sorry this is a forum not English courses I'm in a rush to type.

Learn to use the extra brain power to learn to read run-on's without needing to complain about it being difficult. Takes more intelligence to read a poorly worded sentence than a normal scripted one.


But, I will try to focus a little more ;)
>>
>>7933081
On the ground.. Simple

Even without the forgotten but added AIR RESISTANCE. it still is the matter that the train is moving with you. If Your theory makes sense then when you run on a train you would be moving faster than it. If that happen you would be covering more ground INDEPENDENTLY than the train that doesn't mean count the ground the train covers. only your own. which means you would run out of train to run on in more time than if the train was still. and ways more if the train was going in reverse. running forward on a train will not make you faster than the train. If anything it would make you slower

This. A million times this. End of fucking thread. How is this even debatable?

Imagine you are floating in space and someone is looking at you with a telescope from earth. You have some sort of space gun that shoots a massive projectile (i.e. it's not a laser gun). Take two frames of reference, one in which you are stationary and earth is moving away from you at speed v in the opposite direction that you are going to fire the gun, and one in which the earth is stationary and you are moving away from the earth at speed v in the direction you are going to fire the gun.

The first frame is your own frame of reference, so you fire the gun and it appears, to you (note that this isn't entirely the case. You would be propelled backwards by firing the shot, but this is unimportant since the frame of reference we are talking about here isn't necessarily tied to any sort of acceleration that you, specifically might go, but rather is just about your initial speed with respect to the earth), that the bullet exits with speed u. When we change frames to the frame of reference of the earth (moving at -v as you see it in your own frame, so it might appear to be moving at some speed greater than u after you fire, it would still appear as u to a person that was floating next to you before you fired), we have to add a +v to the speed of objects in our frame, so the bullet, as observed from someone on earth, would travel with a speed u+v.

In the lab frame, yes, but almost imperceptibly so. Say you're running at some velocity [math] \vec { V } [/math] and the bullet flies at velocity [math] \vec { v } [/math] then the net velocity will be [math] V + v [/math]. But since [math] V << v ~ \text { then } ~ V + v \approx v [/math]

You don't need to use relativity for speeds any thing less than about [math] 0.2c [/math].

about the distance a bullet travels in one second if shot from a gun that is moving at a speed approximately equal to the average running speed of a human male.
>>
>>7934330
It's just an easier way to think about it. From your perspective the bullet doesn't go faster, but from a bystander perspective it does.

You could have just said so. I already knew that and still couldn't understand your wall of text.

If you're flying in a plane at 1000 m/s and you fire a bullet from a gun with a muzzle velocity of 1000m/s will the bullet travel at 2000m/s will it just stay in the gun or travel alongside the plane?
>>
>>7934646
It would be 2000 m/s in the lab frame or 1000 m/s in the frame of the plane.
>>
>>7926952
>If you fire a gun while running, does the bullet come out faster than if you shoot standing still.
Yes.

That's why it's military practice to stab forward with your gun as you shoot it for that extra power in bullets.
>>
>>7934646
it would travel ahead of the plane, it's twice as fast
