This is not just true of slinkies – if you release a steel rod from the top, the top really starts falling before the bottom. If you hit a tennis ball with a racket, a wave has to travel from the strings to your hand before you feel it – and the ball is well on its way to the net by this time. If you hit a golf ball, the ball is well on its way to the hole before you can feel it. Rigid bodies aren’t truly rigid and understanding this is essential to understanding the way the world works

This is an excerpt from a video I made 10 years ago – seemed like the perfect thing to show in vertical format. I was unaware Action Labs had recently made a video about the same thing. A regular video should be out Friday/Saturday this week.

Jesus loves you!❤✝️Repent and God bless
For I know the plans I have for you, declares the Lord, plans to prosper you and not to harm you, plans to give you hope and a future.
Jeremiah 29:11
We have finally mastered antigravity
Physics
Ok so a freaking toy just defies physics. Amazing
OK, so what is the "speed of slinky" with which waves propagate inside the spring, and I'm guessing it's different for every kind of spring.
I hope this gets patched soon. Litterally gamebreaking
Imagine if there was a loop… what would happen?
I prefer this—real, tangible phenomenon that can't be examined from a truly scientific standpoint–over imaginary concepts such as black holes and matter bending space-time.
Its the bloody JEE Qs.
