   It’s actually 1/60 of a second.

   If google doesn’t recognize it as a unit of time, then I don’t either!

   Aaaaactuuuaaallyyyy… it’s 3 × 10-24 seconds, or 1/60 of a second, or 1/50 of a second, or 0.01 seconds (which turns out to be… wait for it… 1/100 of a second). Perhaps you should fully parse a Wikipedia article before trying to correct someone next time.

   I’ve got better ones:
   Jerk is the first derivative of acceleration (i.e. how fast acceleration is changing). Makes sense? Now let’s go further…

   “Snap”, “Crackle” and “Pop” are (respectively) the 2nd, 3rd, and 4th derivatives of acceleration. Terminology for these 3 aren’t 100% universally accepted, but they are commonly used in the realm of design of mechanical systems, especially cams.
