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 on 18 Mar 19:49 collapse

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.

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

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.

Can you fucking learn homonyms if you’re going to make an entire ass meme about something?

TheRealKuni@midwest.social on 18 Mar 14:56 collapse

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.

spicystraw@lemmy.world on 18 Mar 14:49 next collapse

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.

Coreidan@lemmy.world on 18 Mar 17:40 next collapse

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.

slackassassin@sh.itjust.works on 19 Mar 03:32 next collapse

Slowing down is negative acceleration if that helps.

spicystraw@lemmy.world on 19 Mar 07:56 collapse

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!

merc@sh.itjust.works on 18 Mar 20:47 next collapse

Breaking doesn’t cause acceleration, it just causes damage.

psud@aussie.zone on 18 Mar 20:52 collapse

spicystraw@lemmy.world on 19 Mar 07:44 collapse

Thanks

dependencyinjection@discuss.tchncs.de on 18 Mar 14:53 next collapse

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.
Crikeste@lemm.ee on 18 Mar 15:53 collapse

Overcook fish? Believe it or not, acceleration.

dependencyinjection@discuss.tchncs.de on 18 Mar 15:57 collapse

Pray tell?

Crikeste@lemm.ee on 18 Mar 16:24 collapse
merc@sh.itjust.works on 18 Mar 21:09 collapse

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.

I’ve never seen a clutch bigger than the brake pedal.

stelelor@lemmy.ca on 18 Mar 20:08 collapse

It could be the handbrake (well, footbrake). If that’s the case, it’s unusually close to the other pedals.

mmddmm@lemm.ee on 18 Mar 21:49 collapse

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.

Gasoline not petroleum.

crmsnbleyd@sopuli.xyz on 19 Mar 02:55 next collapse

Gasoline is called petrol outside of the US. It is a distinct word from petroleum.

merc@sh.itjust.works on 19 Mar 03:41 collapse

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”.

arcane@lemmy.world on 19 Mar 11:57 collapse

No, if there is constant pressure on the accelerator, there is a constant acceleration on the car.
