Hi guys! So I have been learning about jerk/jolt as the third time derivative of distance, and thinking about newtons law of universal gravitation, and I have come to the conclusion that a falling object must have jerk, and even jounce. Here's how I came to that conclusion: The acceleration of a falling object depends on the mass of the larger body (in this case earth) and the distance from the center of gravity. If an object is accelerating towards the earth, the distance from the center of gravity is changing, therefore changing the acceleration (probably a very minimal amount), which means there is jerk. Then, as the acceleration increases, the faster the object's distance from the center of gravity decreases, therefore changing the rate of change in acceleration, and giving the object jounce. It seems as if it could go on infinitely, like how the infinite derivative of an exponential function is not constant (that may be a really bad way of saying that but you know what I mean). Is this correct or am I missing something? Thanks!
