    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.

      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.

        Exactly my thinking, looks like a dead pedal not a clutch.

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

      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)

        Peek and peak upsets me all the time too! “Duel wield” is another one. While we’re at it, people who pronounce melee as Me Lee. It should sound like May Lay.

          I loose my mind with this kind of thing too. Do these people have a screw lose? What kind of rational would a rationale person use to decide to just use similar looking words with different meanings?

          It was almost painful to write that out actually, but don’t worry I’ll add it to the list of things to review in therapy 😂

    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!

      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.
