How a slinky falls in slow motion  

Derek and action lab collab??

I remember this vid

Veritasium and The Action Lab are my favorites science youtube channels😁🙌🏼

someones using reddit

What? Don't apologize for putting out a video similar to the action lab, that guy uses peoples video ideas all the time, and does not credit them.

Until and unless he sees that there's nothing under his feet.

@@kantoumanjigang Then wave at the camera.

@@kantoumanjigang schrodingers gravity

Cuz if u look down, that's when the gravity strikes

Underated af 😂

No because the center of mass of the slinky is still moving downwards as the top is progressively going downwards towards the bottom. So the slinky is still moving, even if the bottom is staying still. So yes, it is falling.

Due to inertia of rest

@@valewind4665 the slinky is falling but the bottom is proof that there is anti gravity potential in coils. We should be looking at this potential a bit more closely for possible travel at high g’s

Exactly

@@truckertruthetrutrucker5357 fair point, but my original point was not to further explain how we could use this to our advantage in anyway, but to explain to op that yes, the slinky is still moving.

Gravity lagged in a second

Try having a helium balloon on a string in a vehicle and then accelerate forward -- the balloon leans *forward* while everything else sways backwards. Doesn't look right at all. It also leans into a turn as you take a fast corner.

Came here to say something like this lmfao Said it like it was some controlled item "It is unlawful to possess a slinky that stretches longer than 10ft without a permit"

More like him saying he didn't have access Orrrrr A means to get a slinky longer than this 😆😅

@@berlinflight_tv 🤣

The one you see connecting a truck and a container

I wish there would be a video seeing something like that

I've thought about that too, but a slinky so long that you could stare at the bottom for a few seconds would probably break under its own weight

Your answer is in 2nd one. It will behave like that.

the center of the gravity of the slinky still follow the rule of gravity. the top of the slinky is accelerated initially with twice the weight of the entire slinky, and no one was complaining about gravity forcing the top portion with double the harshness... Gravity is a F**KING weak dweeb anyways. The entire planet's mass pulling on me can be countered by simply jumping. You know how ridiculous powerful the force of 1 unit of electric charge on another unit of electric charge? That's why we have names like "one absolute unit" we can unify All other forces in the universe, yes even the one Luke used to murder 10 million people in one go, under one equation (E=mc2 ? no idea, too dumb and didn't study), except for Gravity, because it is such a lame weak-a** sauce. Even Eienstein said "F**K it" and gave up on it.

Also springs up another question. What if some mass is dangling on the end of the coil? Will that piece of mass "float" together with the end of the coil or will it fall too?

I'm sure the flat earth community is hard at work to uncover these hidden slinkys.

@@rafetizer we are trying but we haven't uncovered anything just yet, I think they are in the same room as the real globes.

Was it the one from questacon in Canberra Australia?? I think I had the same one growing up lol

some objects are just too powerful for mere mortals to wield

@Peaker’s Lab or rather, *not* begging

Yeah exactly 😁

or are all cartoon characters just slinkys in disguise? is it all just a great conspiracy?

Wile E. Coyote was right! 🤣

🤣🤣🤣

this is gold

Just an illusion, the bottom is just moving up at the same rate as it is falling.

@@IdgaradLyracant well that's equivalent to the bottom isn't moving lol

@@IdgaradLyracant that’s great, but it doesn’t contradict what I said, the top still reaches below the bottom

@@IdgaradLyracant It's actually not. When you hold a slinky, there is a force-ballance between the force you applied to hold it vs the tension force. When you then release the top part, the tension force that hold the bottom part against gravity doesn't instanteniously dissappear. This "information" about the force become zero travels at finite speed to the bottom via the propagating wave on the slinky. Once the wave reaches the bottom part, the tension force that holds the bottom part then become zero and it start to fall down.

haxx

This guy just had a poor explanation... Gravity pulls the slinky as the slinky stretches the force of recoil gets stronger til eventually it stops. When you let it go that upward force against gravity is still being applied while the slinky collapses keeping it afloat til the top meets the bottom and that force is dissipitated

See, a slinky is a spring which means it can be streched or squeeze, and when you drop it, for a slinky to fall down it needs all of its coils squeezed so the slinky wouldn't fall until it's compact like in the first video clip

@@bait5257 that was brutal.

@@bait5257 Oh! lmao

Yes, there is no reason to think otherwise, also the upper part falls faster due to gravity and tension, compensating for the lower part to stay still.

yes, because the acceleration of the center of mass depends on the external force, which here are gravity and the person holding. Compression or elongation will create internal forces which won't affect the com.

gotta get fancy so the viewers see you in slow motion

It implies the existence of longer slinky he DID NOT have access to.

@RU-vid official✔ gravity worked ... The centre of mass of slinky was always in a free fall accelerating at 9.8 m/s^2 ....

@@dev_invc since energy was out to spread it apart once let go it wants to retract back to its original state. Following Newton’s law both ends will converge at the same speed. Since the top is falling at the speed of gravity the bottom is as well. But since it is also being pulled down by gravity the bottom has equal forces which negate each other making it stay in the same spot.

In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled).

@@IlmShadow two great minds think alike*

It's called a Wilberforce pendulum... Highly recommend looking into it for anyone else The weights are to give it a significant moment of inertia, not for sight. If you can get the moment just perfect (such that the rotational frequency equals the natural oscillating frequency of the spring), the system can achieve a resonance that switches between pure rotation and pure vertical oscillation.

@@martyguild i think they meant the spikes were for sight

Lol

@@maple22moose44 indeed they did, but it's not correct. The Wilberforce pendulum, which is what they described, needs to have a mass with an exaggerated moment of inertia in order for the system to work properly. This is accomplished with those "spikes." They are not for visual purpose. Source: I own one.

I’ve kept a slinky from bending

@Hollis2Hollywood Same

But the elastic force depends on the change in configuration of the slinki. So as the slinki starts to move to its original position the eleastic force changes and then both elastic and gravitatiinal forces cant be equal. Then how could the lower end of the slinki be at rest.

@@danishakhtar8148 think of it this way: if there was no gravity at all the slinki woud have shrinked at the midle of its body length. But Since there is gravity , the bottom cannot go up , but will remain at rest until the top of the slinki comes down accelerated by gravity and by the elastic force. Now to answer your question, you are right that the elastic force and gravity are not equal anymore but at the top of the slinki, thats why you see it coming down. When you are holding the slinki you are holding it at the first winding but creating the tension in all of its length. When you release it you no longer are equaling the gravity force on the first winding so it falls while braking the tension to the second winding and so on until the whole tesnion is broke down.

@@adriatikcifliku1346 i don't got what you are trying to say. Plz elaborate

😂

The tool the church needed to deny more science.

Isaac

Basically, the tension of the higher rungs is countering the force of gravity on the lower part.

The slinky obeys physics the tension above and gravity cancels each other's effect.....we had a complete set of problems in physics on this
