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?)
Break Gas? Never heard that expression before. I always thought it was “break wind”. 😆💨
So normal people don’t have an education? It is brake, how do you people keep making this mistake?
Well, I think you answered your own question 😅
Brake.
Petrol. Gas isn’t even a gas.
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 or diesel. Petroleum has to be refined first before use in a car.
Gasoline not petroleum.

gasoline, not gas.
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”.

rofl
I’ll be saving that one
“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!
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.

Though probably not intended, my head canon is that OP is referring to how often people misspell it.
Is it an accelerator? Or is it a jerk pedal? Technically the gas pedal controls the change in acceleration, right?
I definitely have friends
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 🤔
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.
And fifth/sixth derivatives are crackle and pop because some physicists thought it would be funny to have it be “snap crackle and pop”
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?
Increasing speed -> acceleration Decreasing speed -> negative acceleration Changing direction -> Vector acceleration(change in velocity)
Brake*
Sorry, just bugged me ><
depends on if you’re being followed by a cyber truck too closely, or not.
Likewise
NGL I stole this meme and was stoo lazy to fix it
Too*
(You asked for this. Asked for it!)
Stew*
deleted by creator
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
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
You’d be surprised how many “normal” people don’t know the difference
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 😂
Well, it’s easy. If you don’t use the brake, the car could break.
Far left pedal is the clutch, not a second “break”
If you use it wrong enough then “break” becomes the proper spelling.
No, that’s the anti-theft device.
Only works in America though
Unfortunately driving manual is fading away everywhere
As someone who prefers not to drive where possible, and in a country where manual for regular cars is not common, why do people think manual is so great?
Gives you some more control on your gears, sure. But heck, the only time I ever, ever need it is going up or down very steep hills - for which there are low gear settings on most cars which you can switch on for those moments.
For most people, it’s just a massive waste of time to learn, when an engineered solution already exists and presumably doesn’t add significant enough cost to be worth not having it (I assume, because of the lack of demand, here).
Is it just, for the “love of driving”? Okay fair enough, but that’s your hobby then, not sure why we need to like it also
In any case, do enlighten me because I don’t get it haha
First it was the butter churn, then the washboard, and now they’ve come for our clutches
They can pry my butter churn from my cold, dead, and greasy hands.
You will purchase crappy store butter and like it, consumer.
Nah they can have good store butter too. Just no churn.
And there was no one left to speak for me.
BMW was even pushing customers to stop ordering manuals a few years back, so they could just focus on automatics.
Yeah I literally spent 3 years looking for an n55 335i msport manual. And that was almost 10 years ago. Never selling this car lol
No, it’s just a foot rest
I’m on mobile and could be wrong, but this picture looks like it’s an automatic and that’s a foot rest, not a clutch (nearly all Fords have a large plate like that in that spot to rest your left foot)
It’s generally called the dead pedal and yes, it’s basically a footrest for your left foot. This meme is just awful and misspelled brake.
Ahh you know I think you’re right
That looks like a dead pedal (foot rest), not a clutch pedal. Normally only the gas pedal has a full pedal face on it. A clutch pedal normally looks like a brake pedal.
Edit: Eh someone already said this but I agree with them.
Forgot to label Earth as accelerator
Not to mention the driver’s hands and feet!
No, one of them is the “don’t accelerate” pedal you use to switch gears.
You’re applying acceleration to the gear switcher
Just like I’m applying acceleration to your mom
I think that car has a dead pedal, otherwise that is the fattest clutch pedal I have seen by a longshot.
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.
Exactly my thinking, looks like a dead pedal not a clutch.
I’ve never seen a clutch bigger than the brake pedal.
Can you fucking learn homonyms if you’re going to make an entire ass meme about something?
I learned something today.
I was taught in my younger days that “homonyms” were words that were spelled the same but pronounced differently, and “homophones” were words that were pronounced the same but spelled differently. “Break” and “brake” would then be homophones.
But it turns out “homonym” is the broader category including “homophones,” “homographs,” and words where both are true (same spelling and pronunciation, but different meanings). So homophones are homonyms.
TheMoreYouKnow.gif
P.S. Though Wikipedia says a more technical definition would limit “homonym” to, specifically, the third category, words that are spelled and pronounced the same but with different meanings. They give examples of “stalk” (part of a plant) and “stalk” (follow/harass a person), or “skate” (glide on ice) and “skate” (a type of fish).
P.P.S. This reminds me of the autoantonym (a word that is its own opposite) “cleave,” which can mean “to adhere firmly and closely or loyally and unwaveringly” or “to split or sever (something), especially along a natural line or grain.“ I don’t know if “cleave” is technically a homonym, or if these are simply two definitions for the same word, and I don’t know who would decide that. But it’s still a fun word.
autoantonym (a word that is its own opposite) “cleave,”
There’s also “literally”, although I’m not sure if it’s considered an auto-antonym.
Knowing is half the battle…

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.
Love this

“Accelerate… Decelerate” — Simon Phoenix
I don’t get it
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 🤣
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?
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.
Breaking doesn’t cause acceleration, it just causes damage.
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.
Is the window my frame of reference?
