    Acceleration in physics terms just means a change in velocity. Velocity is speed in a given direction

    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.

          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

              Well, it might just have been an out of syllabus thing considering I was not taught that in class and only learnt it while having fun somewhere.
