So normal people don’t have an education? It is brake, how do you people keep making this mistake?
It’s an Alfa, “Break” might be the correct terminology /s
Joke of course, I love Alfa’s!
Well, I think you answered your own question 😅
Likely something to do with English being a secondary language to the vast majority of the world…
Afaik native speakers make such mistakes more often, since they learned far more of the language by hearing than by reading
Love this

There’s this Finnish joke that doesn’t translate well, about a physicist who got pulled over by police. “Uh, I guess I accelerated a bit.”
Tap for spoiler
(A particle accelerator is a machine that accelerates little bits. Do you get it now?)
Okay student, now turn the accelerator and feather the accelerator as you accelerate into the curve, then press the accelerator to accelerate your acceleration out the curve.
To jerk your acceleration*
I don’t get it
I am not smart but this is what I get from this meme.
It’s a play on how physics describes acceleration. In physics acceleration isn’t just about speeding up but any change in velocity.
So:
- Gas = Positive acceleration
- brake = negative acceleration
- steering = velocity takes speed and direction, so acceleration.
Overcook fish? Believe it or not, acceleration.
Pray tell?
In common usage, “accelerate” means “go faster”.
In physics “accelerate” means “change of velocity over time”. It doesn’t just mean that the velocity increases, just that it changes.
In common usage “velocity” is the same thing as “speed”.
In physics “velocity” is “speed in a specific direction”. So, “80 km/h” isn’t a complete velocity statement. “80 km/h going west” is.
So, a car going at a speed of 80 km/h has a velocity of 80 km/h in the forward direction. Pressing the accelerator causes an acceleration in the forward direction, increasing the speed/velocity. Pressing the brake causes an acceleration in the backward direction, decreasing the speed/velocity. Turning the wheel causes an acceleration in the left/right direction. In this case, the speed might not change, but the velocity changes because the direction of travel changes.
If you imagine blowing on an air hockey puck it’s a bit easier to understand. There’s a fundamental rule in Physics that F = m × a, force is equal to mass times acceleration. Or, force divided by mass equals acceleration. If you blow on an air hockey puck, you exert a force on it, causing it to accelerate. If the air hockey puck is moving away from you, blowing on it will cause a forward acceleration increasing its velocity. If you blow on it as it’s coming towards you, you cause an acceleration backwards, decreasing its velocity. If you blow on it as it’s passing by you, you accelerate it sideways. In every case the same F=m × a equation applies, but sometimes the speed gets bigger, sometimes it gets smaller. The trickier one to calculate is when the force causes the direction of travel to change. Then instead of just needing an “x” variable you need “x” and “y”, or if you’re talking about velocity, vx and vy.
So, in a car, the accelerator increases the engine output which causes a force on the tires that results in a forward acceleration. The brake pedal causes the brakes to exert a force on the tires which results in a backwards acceleration. The steering wheel causes the tires to exert a force on the car accelerating it left or right.
TIL that deaccelerate isn’t even a word. My phone is like, wtf is that?
No, but decelerate is.
Ya but it has no meaning because everything is acceleration remember 🤣
Acceleration is a change in velocity. When you press the gas pedal or brake, you feel positive or negative acceleration. When you turn the wheel, you feel sideways acceleration.
Another analogy is force: F=ma. You feel a force if you accelerate, brake, or turn the wheel; all three induce acceleration as defined in physics.
Brake, not break
Thanks
So something slowing down is acceleration?
I still don’t get it. Surely the definition of acceleration is a lot more than just a change in velocity.
But I’m just a dumb ass so don’t listen to me.
Yeah, I get what you mean. So, “acceleration is how fast an object’s speed changes”. See, hitting the brakes or the gas are both acceleration, physics-wise. But not usually how we talk about it.
It’s easier to grasp when you’re doing the calculations.
You’re pretty smart to ask and dig deeper!
Slowing down is negative acceleration if that helps.
Breaking doesn’t cause acceleration, it just causes damage.
Physicians: “It’s all vector addition and differatials?”
Mathematicians: “Always has been.”Brake*
Sorry, just bugged me ><
Likewise
NGL I stole this meme and was stoo lazy to fix it
Too*
(You asked for this. Asked for it!)

was stoo lazy
idk wash she?
There’s an “s” in front of the “too”.
and was stoo lazy to
Too lazy
No fix for you
No it’s definitely “too”, no “to”. Too is a statement of how much, to is a statement of direction. OP is not going toward lazy.
He may have meant stew
Stew*
depends on if you’re being followed by a cyber truck too closely, or not.
You’d be surprised how many “normal” people don’t know the difference
Well, it’s easy. If you don’t use the brake, the car could break.
Peek and peak upsets me all the time too! “Duel wield” is another one. While we’re at it, people who pronounce melee as Me Lee. It should sound like May Lay.
I loose my mind with this kind of thing too. Do these people have a screw lose? What kind of rational would a rationale person use to decide to just use similar looking words with different meanings?
It was almost painful to write that out actually, but don’t worry I’ll add it to the list of things to review in therapy 😂
Any change in velocity, amirite?
*BMW drivers
Well, with Alfas half of those accelerators probably don’t work!
(Actually jk, afaik this is only an old-timey joke now)
Is the window my frame of reference?
You wouldn’t be able to press a gas with your foot though.
Gasoline is a liquid.
Only under certain conditions.
ok sure, but that’s true for you and me as well.
Like normal conditions?
I can imagine a scenario where you a gas is encased in a volume that you can reduce by stepping on it with your foot, thus pressurizing it.
Depends on what you mean by “press” really
Moving your foot through a gas will displace the gas, and there will be a (albiet small) pressure difference around the foot as it moves through the gas. An increase on the side in direction of movement, a decrease on the opposite side of direction of movement, and some vortices on the sides.
Basically a very poorly designed wing.
No, one of them is the “don’t accelerate” pedal you use to switch gears.
I think that car has a dead pedal, otherwise that is the fattest clutch pedal I have seen by a longshot.
Exactly my thinking, looks like a dead pedal not a clutch.
I’ve never seen a clutch bigger than the brake pedal.
It could be the handbrake (well, footbrake). If that’s the case, it’s unusually close to the other pedals.
And way too large, and way too low.
Handbrake pedals are usually small pedals, away from the others and raised so it’s uncomfortable to reach them.
You’re applying acceleration to the gear switcher
Just like I’m applying acceleration to your mom
Is it an accelerator? Or is it a jerk pedal? Technically the gas pedal controls the change in acceleration, right?
I definitely have friends
Technically the gas pedal controls the change in acceleration, right?
Technically it controls the amount of air and/or fuel delivered to the engine (in a gas engine, the pedal directly controls airflow; in a diesel engine it directly controls fuel flow)
A valve controller, yes
Acceleration in physics terms just means a change in velocity. Velocity is speed in a given direction. The steering wheel, gas pedal, and brake pedal all accelerate the vehicle.
Acceleration in physics terms just means a change in velocity. Velocity is speed in a given direction
They definitely know that, given that they know that change in acceleration is called jerk
And I had no idea what the fourth derivative was called so I had to look it up. It’s called snap or jounce.
I remember when my calculus professor offhand mentioned these and jerk. He had a really dry sense of humor, so I didn’t realize that he wasn’t joking with us (the class) until like two semesters later.
So, you didn’t realise that during the unit test?
If I remember right, it wasn’t on any test. Those tests were all problem solving, and none of the problems had derivatives deeper than acceleration. It was awhile ago though, I could be misremembering
Well, it might just have been an out of syllabus thing considering I was not taught that in class and only learnt it while having fun somewhere.
And fifth/sixth derivatives are crackle and pop because some physicists thought it would be funny to have it be “snap crackle and pop”
Increasing speed -> acceleration Decreasing speed -> negative acceleration Changing direction -> Vector acceleration(change in velocity)
No, if there is constant pressure on the accelerator, there is a constant acceleration on the car.
The jerk comes with the rate of change of pressure on the pedal (e.g. if you stomp on it)
That would make the driver the jerk 🤔
Brake.
Though probably not intended, my head canon is that OP is referring to how often people misspell it.

Petrol. Gas isn’t even a gas.
Rich, from the kind of person who thinks there’s an F in “lieutenant.”
I’m guessing you pronounce Colonel as Kernel.
As if cutting letters and syllables from words to make then more efficient isn’t a tradition as old as words, innit?
But adding an invisible consonant? That’s insane.
It’s not because of efficiency or whatever you’re trying to say (and saying Kernel literally adds an R), military ranks especially have a long history of crossovers in languages and weirdness in pronunciation and spelling. And all 3 aren’t in line.
Like wow it’s ok to not know these things, but you shouldn’t act all holier than thou. Ciao.
Fuck’s sake, you were taking my comments as serious elitism?
Touch grass, my guy.
So either 1) you were wrong and now hide, or 2) you’re trolling, weirdly at that. Either way, that means you’re the one that needs to touch grass. Have at it, ciao.
I’m not British - but I am a Physicist.
Then you should know the difference between petroleum and gasoline.
*Gasoline or diesel. Petroleum has to be refined first before use in a car.
“Gas” doesnt refer to its state of matter, it’s short for gasoline.
Wow, I did not know that! I literally have never heard the word “gasoline” before!
Ok, then how about the directional circle, solid pedal, and liquid pedal?
They’re all just vector appliers.
But it was originally derived from coal gas back in the 3rd quarter of the 19th century, when the first internal combustion engine for transportation application was being developed.
Gasoline not petroleum.
Gasoline is called petrol outside of the US. It is a distinct word from petroleum.
I’m aware that British people think it’s called petrol, but you’re mistaken if you think that it’s only the US that calls it Gasoline. That’s the term used for most of the English-speaking Americas, including Canada and many former British colonies like Bermuda and the Bahamas. In fact, if you include Latin America’s “gasolina” it’s almost the entire Americas. And if you include variants on that name you’ll also have to include Japan and Korea. In fact, “gasoline” has even invaded the British isles. Variations of “gasoline” are sometimes used in Welsh, Scots Gaelic and Irish.
But, anyhow, my point was more that “gas isn’t even a gas” is as dumb as “petrol isn’t even petroleum”. “Gas” is just a short form for “gasoline”, nobody’s suggesting it’s in a gaseous state, just like nobody is suggesting that petrol is literally just a short form of petroleum, despite the obvious similarity of the words. This is English, the language where “read” and “read” are two different words pronounced differently. It’s no major issue to have “gas” be a short form of gasoline as well as being a state of matter, though it does sound funny if you say something like “gas is a liquid”.

gasoline, not gas.
Forgot to label Earth as accelerator
Not to mention the driver’s hands and feet!
