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)

Increasing speed -> acceleration Decreasing speed -> negative acceleration Changing direction -> Vector acceleration(change in velocity)

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.

Petrol. Gas isn’t even a gas.

You’re applying acceleration to the gear switcher

I think that car has a dead pedal, otherwise that is the fattest clutch pedal I have seen by a longshot.

No, that’s the anti-theft device.

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.

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)

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.

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.

You’d be surprised how many “normal” people don’t know the difference

depends on if you’re being followed by a cyber truck too closely, or not.

NGL I stole this meme and was stoo lazy to fix 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.

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.

Not to mention the driver’s hands and feet!

Well, with Alfas half of those accelerators probably don’t work!

(Actually jk, afaik this is only an old-timey joke now)

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.

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.

Gasoline is a liquid.
