Solving SPRING PENDULUM with NEWTONIAN MECHANICS

In this video, I will solve the SPRING PENDULUM using forces and Newton's second law, just as in my previous video where I did the same with the double pendulum.
This system is far easier to tackle with Newton, it can be done much easier in pure cartesian coordinates too, but I used polar coordinates, as the equations in that system look much better, and they are the exact same you would get with Lagrangian method.
If you have any questions about the derivation, feel free to leave a comment, and we'll discuss it there. You can check my video on the double pendulum:

I hope you enjoyed the video and learned something new. Thank you for watching:)
