    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)
