- AnimalMuppet 2y agoExcept that non-calculus, non-physics people don't know what jerk is. If you try to explain, they'll decide that it's you ;-)
- beerandt 2y agoYeah, but that's actually what draws renewed interest about half the time, as a TIL. And if neither that or the overall comparison works, you probably never had a chance anyway. ETA- And 9/10 when I use it, it's in the context of engineering, explaining pavement damage and impact loads or similar. It's a great early tell for which version of the explanation you're going to get.
- bryanlarsen 2y agoJerk is accelerating acceleration. Acceleration is the feeling you get when you're pushed back in your seat in a car or amusement park ride. Jerk is what happens when the depth into your seat is increasing (or decreasing).
