5 Ways to Model a Swinging Pendulum

[@r4fa3l59]

This is great. People need to understand physics is not just memorizing a bunch of formulas but actually perceive that it is mathematics applied to model our real world, so i think it plays a major role in our development as humans.

You seem like the last in the line of true Physicists: normal people who can joke, swear, have quirks, aren't easily categorised but are incandescent as a result of their passion for Physics. Your videos really are illuminating and they do make me a better Physicist myself. I'm actually a Doctor of Plasma Physics, although you'd never know from this account.

thanks for the feedback. I'm glad you enjoyed - I obviously have lots of fun talking about physics.

[@nolan8377]

Loved it. Going through advanced mechanics right now and this is a great example to show all the methods.

😱 omg, for the first time I actually understood it.

Very useful diverse methods for Modelling a Pendulum specially for Control Systems Engineers and Scientists. Besides, Newton 2nd Law, Angular Momentum and Torque Equations, Hamiltionan Mechanics, Differential Equations by Numerical Methods [Euler, Runge Kutta....], Euler Lagrange Equations I will add the sixth one: Neural Network Inverse Modelling and a seventh one: System Identification - Parametric Estimation [System ID]. Great video , very useful !! Pd. Please, what is the name of the Physics Professor so I can follow him on the networks? Thank You.

Hello there. Excellent video, by the way. I just wanted to ask if you will work on that video talking about how you do the pedulum and spring animations with Python, as you've stated. First time I watch your content and I am amazed by your dedication and obvious love for Physics. Thanks!

[@smoosq9501]

wow, well explained, thank you for the work!

[@rbmfavourites7122]

Thanks

[@DotPhysics]

thank you very much!!

[@mariomuysensual]

Excellent video

[@DotPhysics]

Thank you very much!

[@fizixx]

Nice video. Always enjoyable. :)

[@Animal-yb1rr]

I want to build pendulum in my room and make it swing automatically I like your channel very much

[@astro6393]

great video but I didn't understand how you translated the net vector force in the last method to a numerical approximation of the position. Seeing the original code would be helpful.

Isn't the kinetic energy L(1-cos()) since it's the height taken away from the bottom?

[@DotPhysics]

maybe you are thinking about the potential energy? But then, it depends on where you set y = 0, I put y = 0 at the pivot. If you redefine y =0 at the bottom, you get the same equation in the end.

please remake the video

It shouldn't be too hard to use \mathcal{L} for Lagrangian in the script that generates the equations, cut out the discussion of the ambiguous variable, and thus fix the video.
