Lagrangian in Polar Coordinates (8.5)

[@grislygranger8983]

Thank you for this sir. I have a question, will we get the same angular and radial if we have U(r, phi)?

Thx from india sir

@ 7:11 All of us know that, when the derivative of "anything" with respect to time is zero, this "anything" is a constant. Next time, first write your equations down and then comment on them.

WARNING: The only potential in this video is in the red box and is called U(r). In my opinion, this is a bad choice for educational reasons; my potentials are in volts (V). Even worse, all the other U's in the video are potential energies; even though he keeps calling them potentials most of the time.
