Ya jerk.
>>8176789
What is the change in jerk? Or the change in the change in jerk
>>8176764

Unit known as chad

I'm not sure they have names beyond that
>>8176839
jounce
>>8176867
Is it safe to assume that if you have change position in your life you have experienced the infinite series of derivatives of the position vector.
>>8176871
Bump this
[(Meters per second) per second] per second = m/s^3?
position, velocity, acceleration, jerk, snap, crackle, pop.
and so forth it to more and more autistic names
>>8176890
If an object has a pop of 1m/s^6, how far would it have traveled in meters relative to point A after 10 seconds
>>8176764
Acceleration is if you turn too. It simply means "a change in inertia". Acceleration is change in direction as well as speeding up or slowing down. "Decceleration" is not a word, wven if you're slowing down it's called accelerating.

Upvote for you m'anon
*tips fedora*
>>8176898
Ok deceleration is a word technically, but in physics we always refer to it as an acceleration still. All terminology
>>8176897
You would need more information than that to answer the question. You'd end up with a bunch of unknown functions because the initial conditions of crackle, jerk, acceleration, and velocity are all unknown. Even if you you're only worrying about acceleration, the end result would still contain a function depending on initial velocity. If the abstract answer is what you're looking for, well, that wouldn't be that hard, just integrate until you have position.
>>8176935
position, velocity, acceleration, jerk, crackle and all other values are zero except pop, which is 1 m/s^6. now haw far will it be?
>>8176898
> a change in inertia
a change in velocity.
a change in inertia is something else.
>>8176944
You can't have pop without speed dipshit.
>>8176867
What are they used for?
>>8176968
Jerk can be used whenever you have a time-dependent force.
I know minimum snap paths are used in control of quadcopters
I think I've read papers that talk about jounce
>>8176978
Really dumbest post all day? Explain how you can have speed without acceleration let alone have pop without speed.
>>8176968
Remember the first time you drove a car and you couldn't smoothly decelerate to a full stop without the car jerking right before stopped? That's jerk: your rate of acceleration wasn't constant therefore you experienced jerk
Like >>8176883 said you have experienced the infinite series of derivatives of the position vector
>>8177028
You clearly are a high schooler. Please stop, it's embarrassing.
Have you never heard of zero starting conditions?
>>8176944
you have 1m/s^7 pop, at the end of 10 seconds your crackle goes from 0 to 10m/s^6
snap goes from 0 to 55 m/s^5
jounce goes from 0 to 1540 m/s^4
jerk goes from 0 to 1,186,570 m/s^3
acceleration goes from 0 to 703,974,775,735 m/s^2
velocity goes from 0 to 247,790,242,435,923,759,782,980 m/s
with 1 pop for 10 seconds you've accelerated to about 825 trillion lightyears per second and are 3.24 decillion lightyears away from earth
>>8177085
sorry I did the last part wrong, it's actually only 26 million lightyears per second, so you've traveled 342 trillion lightyears

>Explain how you can have speed without acceleration let alone have pop without speed.
It's been a long time since I took physics, but if acceleration is the derivative of velocity, and if velocity is constant.....then the derivative of a constant is ????

What is the integral of distance?

Absement. Occasionally useful.

>>8176764
Not terribly useful?

That's pretty cool, TIL, but
>The word "absement" is a portmanteau of the words "absence" and "displacement". Similarly, "absition" is a portmanteau of the words "absence" and "position".
KYS whoever is responsible for that.
It's missing snap, crackle, pop unfortunately
>>8178458
Jounce is Snap, but yes. Abserk is clearly the stupidest, from there it's hard to say.
>>8177721
no, and im being completely serious here
I heard a long time ago that
8 is lock
9 is drop
10...idk
>>8176847
Glad somebody had a competent teacher.
>>8178458
yes, unfortunately
>>8178475
Anyone that says 'snap' I immediatly dismiss as a mathfag which obviously makes them useless.
>>8178458
Never thought of the integral of displacement. What use could it have? Love trivial shit like this.

First dervative of position is velocity not speed.

Yes and anti-chads are known as Staceys. A change in Russia is known as a Блaт. A change in change is measured in taxes. And a change in measurments of changes names is measured in changes of measurement which are measured in changes of measurement which are measured in changes of measurement which are m...

is S dt an anti derivative or an integral?
The derivative with respect to time of acceleration is called jerk, and it is a vector.

>>8176867
I thought Jounce and Snap were interchangeable names for the same derivative?
Then the 4th, 5th, and 6th would be Snap Crackle and Pop. Not Jounce, Snap, and Crackle.
>>8182751
You're correct, he dun fucked.
>>8176768
outstanding post
>>8182682
Ever notice how when you're driving you can gradually apply the brake, or just smash your foot down?
That's a physical example of jerk; and you can literally feel the jerk forward.
>>8176897
>r(t) = r(0) + v(0)*t + 1/2*a(0)*t^2 + 1/3*j(0)*t^3 + 1/4*s(0)*t^4 + 1/5*c(0)*t^5 + 1/6*p*t^6
so for
>r(0) = 0
>v(0) = 0
>a(0) = 0
>j(0) = 0
>s(0) = 0
>c(0) = 0
>p = 1m/s^6 and t = 10s
we get
>r(t) = 1/6*(1m/s^6)*(10s)^6 = 166666.67 m
>>8183565
So jounce would be the change in jerks you feel if you, for instance, slammed the brakes, let off, and slammed them again in rapid succession?
it's some stupid tensor field that describes changing metrics. literally why?
>>8183594
I'm not a Physicist so I'm not 100% sure; but I think that would work as an example of jounce.
>>8176867
engi here, i thought you were memeing but this actually exists
