How a slinky falls in slow motion #shorts

Показать описание
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.

It's like in cartoons when the character runs off a cliff, but is still running on the spot and falls seconds later.

Slinky: **isn’t falling**
Gravity: wait that’s illegal

"This is the longest slinky I have access to"
Implying there's longer slinkies but they're in secret underground vaults protected by the pope

The slinky is just like a Cartoon character when He sees that there's nothing down beneath him, He falls.

I think this proves it. Slinkies are magic.

Now I wonder what happens when you get a REALLY long one and drop it from really high. Would it look like it’s floating for a couple seconds? If so then cool

“That is the longest slinky I have access to.”

The question is, what slinkies do you NOT have access to?!

Crazy how the top of a slinky can get beneath the bottom before the bottom starts moving down

gravity: "exists"
slinky: you might have to wait for this to happen

This is the most counterintuitive thing I've ever seen.

Slinky: **defeats gravity**

Newton: "son of a bitch!"

Actually this was a bug added back in the Matrix’s 5.14 update but never removed due to the engines mechanics

The fact that a slinky is capable of defying physics explains why its arrangement gets screwed up after 10 minutes has been spent playing with it.

Newton: “*The force of gravity affects everything with mass in the universe*”

Slinky: “And who decided that?”

What nobody mentions here is that the center of mass of the slinky still falls at 9.8 m/s2 (i.e. it is free falling with the acceleration of gravity), which means that, to compensate for the bottom coils not falling, the top coils are falling much faster than what they would if you just cut the top few coils and dropped them alone. An the reason is simple: The same tension that is pulling up on the bottom coils cancelling the force of gravity, is pulling down on the top coils adding to the force of gravity.
