    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 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)

      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.

        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.

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

          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”.

    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.

        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.

    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.

      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.
