Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

This makes it a seem like a circular problem that is impossible to solve (it's not actually impossible). So, the key in the numerical calculation is to break this problem into short time intervals.

Here are 6 tips to solve Physics numerical problems quickly; Understand Concepts Thoroughly Ensure you have a strong understanding of the underlying physics concepts involved in each numerical ...

Sure, you could avoid all physics problems in which you have to solve for two variables but that might be a bit silly. The same is now true for numerical calculations.
