Hello, I was doing some research on differentiating kinematics. For example, differentiating displacement will give you velocity, and differentiating velocity gives you acceleration. When you differentiate acceleration apparently you get something called "jerk" (wow what a jerk). And when you differentiate jerk, you get "jounce". Can someone explain to me what jerk and jounce are in like real life? What are some examples of each and how do they work?
