    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)

    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.

      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.
