No, it’s just a foot rest
BossDj@lemm.ee 2 months ago
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)
imsufferableninja@sh.itjust.works 2 months ago
Ahh you know I think you’re right
Trollception@sh.itjust.works 2 months ago
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.
SpermHowitzer@sh.itjust.works 2 months ago
If you use it wrong enough then “break” becomes the proper spelling.
Bytemeister@lemmy.world 2 months ago
Brake.

*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.

Ok, then how about the directional circle, solid pedal, and liquid pedal?
Eagle0110@lemmy.world 2 months ago
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.

Not to mention the driver’s hands and feet!
Brosplosion@lemm.ee 2 months ago
Is it an accelerator? Or is it a jerk pedal? Technically the gas pedal controls the change in acceleration, right?
I definitely have friends
Revan343@lemmy.ca 2 months ago

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
DrSteveBrule@mander.xyz 2 months ago
Acceleration in physics terms just means a change in velocity. Velocity is speed in a given direction. The steering wheel, gas pedal, and break pedal all accelerate the vehicle.
Revan343@lemmy.ca 2 months ago

They definitely know that, given that they know that change in acceleration is called jerk
mexicancartel@lemmy.dbzer0.com 2 months ago
Increasing speed -> acceleration Decreasing speed -> negative acceleration Changing direction -> Vector acceleration(change in velocity)
arcane@lemmy.world 2 months ago
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 🤔

So normal people don’t have an education? It is brake, how do you people keep making this mistake?
Ronno@feddit.nl 2 months ago
It’s an Alfa, “Break” might be the correct terminology /s
Joke of course, I love Alfa’s!

Likely something to do with English being a secondary language to the vast majority of the world.
FooBarrington@lemmy.world 2 months ago
Afaik native speakers make such mistakes more often, since they learned far more of the language by hearing than by reading

Can you fucking learn homonyms if you’re going to make an entire ass meme about something?
TheRealKuni@midwest.social 2 months ago
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.

No, one of them is the “don’t accelerate” pedal you use to switch gears.
Natanael@infosec.pub 2 months ago
You’re applying acceleration to the gear switcher
0ops@lemm.ee 2 months ago
Just like I’m applying acceleration to your mom
Bytemeister@lemmy.world 2 months ago
I think that car has a dead pedal, otherwise that is the fattest clutch pedal I have seen by a longshot.
stelelor@lemmy.ca 2 months ago
It could be the handbrake (well, footbrake). If that’s the case, it’s unusually close to the other pedals.
Gormadt@lemmy.blahaj.zone 2 months ago
Exactly my thinking, looks like a dead pedal not a clutch.
I’ve never seen a clutch bigger than the brake pedal.
credo@lemmy.world 2 months ago
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.

I don’t get it
dependencyinjection@discuss.tchncs.de 2 months ago
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 is just about speeding up but any change in velocity.
So:
- Gas = Positive acceleration
- brake = negative acceleration
- steering = velocity takes speed and direction, so acceleration.
Crikeste@lemm.ee 2 months ago
Overcook fish? Believe it or not, acceleration.
spicystraw@lemmy.world 2 months ago
Acceleration is change in velocity. When you press gas or break you can feel positive or negative Acceleration. When you turn the wheel you will feel Acceleration sideways.
Another analogy is force. F=ma. You feel a force if you accelerate, break or turn the wheel, so all three induce Acceleration as defined in physics.
merc@sh.itjust.works 2 months ago
Breaking doesn’t cause acceleration, it just causes damage.
Coreidan@lemmy.world 2 months ago
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.
merc@sh.itjust.works 2 months ago
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.

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?)

You wouldn’t be able to press a gas with your foot though.
b34k@lemmy.world 2 months ago
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.
Gormadt@lemmy.blahaj.zone 2 months ago
Depends on what you mean by “press” really
Moving your foot through a gas will displace the gas, and their 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.

Well, it’s easy. If you don’t use the brake, the car could break.
