if you had a pendulum above ground, at the equilibrium point wouldn't there also be potential energy? Same for the spring with the block pulling down right? so why is KE the total energy at those points --> i think around 18:30 you said KE at equilibrium is TE? or is it just that for the purpose of the questions its easier to solve if you consider it like that for pendulums?
If you watch the beginning of this video ruclips.net/video/CERrHHW9Pa8/видео.html I explain why the vertical spring system can be treated like a horizontal spring system. We simply take our displacement from the equilibrium position for the hanging mass, rather than using the uncompressed spring position, and we ignore the gravitational potential energy. This video is very useful. ruclips.net/video/FKltat9EHqw/видео.html
the child screaming at the end🤣
My daughter makes a few cameos.

@@donerphysics thank you!
Thank you very much
at 1:14 where is the restoring force getting its energy from? and why does this phenomenon happen?
We are typically talking about a mass on a spring. Push the spring in and it pushes back. The object on the end of the spring will oscillate.
