Lets suppose that we setup two instances involving two masses m1 and m2. m1 > m2 Case 1. The two bodies are separated by a distance r = 20. Case 2. The two bodies are separated by a distance r = 10. Suppose that in both setups, we were to release all restraining forces on these two bodies at once and let gravity have its way. Both the accelerations will increase over time because r is decreasing but is the jerk of both cases equal?
