How a slinky falls in slow motion
소스 코드
- 게시일 2021. 07. 18.
- 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

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

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
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?

@Peaker’s Lab or rather, *not* begging
The center of mass of that slinky is dropping as the top of the slinky falls. Since the center of mass is falling the lower portion of the slinky doesn't need to fall till the center of mass reaches the point where it is no longer shrinking as the top collapses. This would be the same as if you put it on an elastic band.
Same thing the earth does
Centre of mass of slinky should at the centre of the slinky but at first it isn't moving.
That's not how it works 😊
@@homeworkofficial I am reading this about a month later, but what original comment said is 100 percent valid. During free fall, geometry of slinky is changing, and C.O.M isn't exactly half way between topmost and bottom most part of slinky .

Crazy how the top of a slinky can get beneath the bottom before the bottom starts moving down
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
Thank you epic science man

@Dont Read My Channel Banner 😂
Ur welcome
@@australianoutback very well said brother, the government has some unbelievable conspiracy theories
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.
The center of gravity continues to fall towards earth and this is a good visual of where the center of gravity is at all times
I think this proves it. Slinkies are magic.
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

The real question is: is the centre of mass falling at the same speed as if u dropped the slinky uncompressed
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.

Well for those looking for an explanation , the force in a spring/slinky doesnt change instantly and thus the lower end remains in equilibrium for some time even after the upper end has been released because the tension applied by the part just above it has pretty much balanced its weight like it had before the slinky was released and thus equilibrium is maintained for a while.

Much better explanation than what I've sometimes heard about how "the bottom doesn't know the top has been dropped yet" as though it was somehow falling at the speed of light.
The force pulling it back together is perfectly cancelled out by the force making it fall, so it doesn't do either.

@@highq9039 it's a slinky bruh what's it gonna do?
Do you know what wind is?
In one of my college physics classes, the professor had a demonstrator showing how linear and rotational motion are coupled in a spring. It was a very long/light spring (essentially a slinky) suspended from the top and with a weight at the bottom. The weight had spikes coming out of it sideways to make easy to see it rotate. He pulled the weight down and we watched bounce up and down, then transition to rotation until the weight was oscillating CW/CCW and then transition back. That was cool until we had to explain it!
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.

A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably.[1] The English word was introduced in ca. 1570 - when early handguns were produced in Europe and is derived from the Middle French pistolet (ca. 1550), meaning a small gun or knife. 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).
A government-issue M1911 pistol manufactured in 1914

Soviet TT pistol manufactured in 1937
The most common type of pistol used in the contemporary era is the semi-automatic pistol, while the older single-shot and manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict laws and regulations governing their manufacture and sale.:full_moon: :waning_gibbous_moon: :last_quarter_moon: :waning_crescent_moon: :waxing_crescent_moon: :first_quarter_moon: :waxing_gibbous_moon:

It actually happens that when the top of slinky reaches bottom of slinky it speed is 19.6m/s and then there is a delay same the time taken for the connection of top and bottom of slinky and then it continues falling at normal rate thats why when slinky and other object are thrown together they touch the ground at same time even though the other object has travelled the half distance at the same time when slinky top reaches bottom.

Elastodynamics.. I think the compressional wave still travels faster than any other wave, such as the rotating/twisting one. The problem is, that this compressional wave (which you could sense by detecting minor vibrations felt at the bottom, since early on) has a waveform, a shape vs time, and this form starts very very mildly with small amplitudes that only become important/high later on and that is what we observe as the progressing contraction of the slinky..
I'm amazed by this, tension is over powering gravity, the energy transfer is easily done in an equation but even understanding the physics behind this still boggles me.

Gravity: who defies me?
Gravity: *exists*
Slinkies: well yes but actually no
There are 2 force acting on both the ends of the slinky. 1) Gravitational and 2) Elastic force. The Gravitational and Elastic force acting against each other on the bottom end the slinky and cancelling out each other so instead of going down it is held at the same place while the the top end is accelerated by both gravity and tension through elastic force acting from same direction.
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
Wow! Is it like the bottom one is pulling up to the one above it? So cool thanks for sharing!!
Exactly! It is still accelerating down, but is also pulled up by the tension :)
The corallary, which he doesn't explictly mention, is that the top is accelerating much faster than 9.8 m/s² (the acceleration rate of gravity on earth in a vacuum). Not only is it the top of the slinky being pulled down by gravity, it's also being pulled down by tension - the same force which is pulling up on the bottom and preventing it from falling.
So in other words, the mass Centre actually falls at a normal acceleration of 9.81..m/s^2

@@Alexander-vs2ee you must be boring as hell in parties, which is also the reason that you aren't invited to them. 😐
The reason is that last portion of slinky also apply the force in the opposite of gravity and stronger then gravity.
Slinky: *floats*
Gravity: wait that's illegal....
2 things I've never accomplished: Finish a tube of chapstick without losing it and keep a slinky from bending
I love this
Also using up an eraser without losing it
Chef's kiss i love your comment 😘😌💅
I’ve kept a slinky from bending

Slinky:Was that a ghost?!!
This is new to me. I found it fascinating, given “gravity” and all. Thank you for sharing!
After this slinky invented, the cartoon physics was born
Maybe after that
@@jennie-sz9vp maybe it’s a joke
Issac: Gravity is real.
Slinky: Imma about to end this whole man's career.

The tool the church needed to deny more science.

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
Everything science till slinky goes upwards
I've always had a question. Wouldn't the whole system fall, because gravity should exert its force on all points? Or, is it a multi-point/body system, this the force exerted by gravity is countered by the stretching of the slinky and thus the top (heavier part) needs to come down first for it to fall?
Imagine cutting it in half mid air and throwing the top part away. That way the botton half would stay suspended forever. I love physics!
@Cyclovizioned shhhhh he doesn't know, and it may be better that way.
@@aaronwilliams8887 issa joke
@@ispres so is mine mate 😉
Everyone thinking this comment is a joke, no, it isnt, the commenter is from a type 2 civilisation where they use this technique to build huge structures without having to build the base first, the reason it doesnt work when we try it is because the slinky needs to be cut in exactly half, down to the last quark, however this isnt possible with our earthian technology
@@user-ht6ql1rn3w how do you know this?
Slinky’s be like: “gravity? never heard of her”
Lol I was thinking of commenting something kinda like this but then I saw this
Underrated comments 😂😂
Thought gravity was just gravity not a gender?
Oh so gravity has a gender now?
@@HanazukaNo.2 that's what I said, I think they were thinking of mother nature but still it can't have a gender cause gravity is on every planet with an atmosphere I think
Slinkie: *doesnt fall*
me: I CAN FLY NOW!
also me: *dead*
Hypnotic. The top is still pulling the bottom up from the force of gravity - while the top itself is now falling. (Reminds me of the line from the first Superman movie, when he rescued Lois falling from the top of the Daily Planet building: “Easy, Miss, I’ve got you.” “You’ve got me? Who’s got you?!”)
Bottom loop be like: guys why we turning? Say what somebody dropped us? 😲
That's when you realize that stretching it doesn't just spread it out but "UN-twists" it as well.

@@Villerkai yuh
@@Villerkai I don’t 🙁
You should look at the acceleration of the top's motion (and calculate it). Since the center of mass of the whole slinky system must accelerate at 9.8m/s², and the unupdated slinky half has an acceleration of 0, the top must accelerate faster (which is easily explained, since both gravity and slinky tension are accelerating it).
The top of the slinky: *falls*
The bottom: “I can wait”
