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.

    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.

    So, you didn't realise that during the unit test?

    If I remember right, it wasn't on any test. Those tests were all problem solving, and none of the problems had derivatives deeper than acceleration. It was awhile ago though, I could be misremembering
