The energy in the universe never increases or decreases -- but it does move around a lot. Energy can be potential (like a stretched-out rubber band waiting to snap) or kinetic (like the molecules that vibrate within any substance). And though we can't exactly see it, every time we cook dinner or shiver on a cold night, we know it's there. George Zaidan and Charles Morton get excited about energy.
Lesson by George Zaidan and Charles Morton, animation by Pew36 Animation Studios.
The chameleon phoenix. Best name for energy ever!
Factoid except different arrangement haha.
energy...a chameleon phoenix. What a way to describe it!
I have to say that you guys always put out high quality material. You're doing the future generations good by providing truly accessible knowledge. Thanks!
0:10 Two blue molecules conspired to push an orange molecule into the fire. That is messed up.
Actually, if you look more carefully, it's one.
Bro thats SOOO Messed up
Brilliant job, Ted-Ed.
Thank you for your effort
Make more of these videos with the robots
MO, if you watch wall-e
Yes yes
very good quality video, ted-ed are stepping it up!
As a student of life I am here to learn, grow and share. ... Here is something interesting. Pass it on.
that’s amazingly well explained
best educational animation ive ever seen
Energy!!! I love this ed
really beautiful!!
Awesome!
Those arent the robots from the cell video?
We need more robot factory animations on TED-Ed. Keep it going.
This robot theme is the best theme I have ever came across on your channel. Make more robot theme videos.
Id love to see these animations in a game
I love these little robots! :D
2:40- oh my gosh!
I thought this was going to be about the sum total of energy in the universe, which equals zero. Would be an interesting video...
Interesting point! But that requires us to introduce « negative energy » which, if I understand it right, is what we call, for lack of a better name, « dark energy ». But that is only relevant at the inter-galactic cosmic scale. As far as I know, on and around earth and within our galaxy we’re stuck with only positive (mass) energy. But of course we have + and - electromagnetic energy. Maybe physicists can clarify this better for us - and yes, a new presentation on that would be great. Cheers!
Thank you for the regurgitation of newton and E=mc^2.
best one from ted ed
Good information❤❤❤❤👌thank u
Best animation!!! so cool
"molecules are always moving. They're not necessarily going somewhere... though they could be..." *shifty eyes*
Now I came to know the concept of Temperature.. thanks Ted Ed
Cool animation.
good job
The fact that we can't describe energy leads to the idea that it's just a philosophical construct, which leads to the idea that nothing really exists ! That it's all imagined.
Best answer so far
Didn't mention conversion into matter or from matter to kinetic energy in fission or (hopefully in the future) in fusion. Nevertheless this is a well put together and informative video which I would like to commend greatly for it's style.
nice one
holy shit that was great video :) pls dont stop
very neat.
Whoa! Phew! Glad!
Deep last line
All of the energy in the universe is... free
Well.. infact, ACTUALLY...
I've seen energy that could only dream of being free. It was imprisoned around a person's waist.
Imagine a person as big as a grizzlybear, with the movement of a penguin.
He was the gulag of energy.
I would not be surprised if this sudden energy stasis of such magnitude is the cause of much unbalance in the world today. All this energy would be out there, spreading harmony to the winds and the seas. Now we have global warming and unrest.
Perhaps when he dies, the planet will heal. The astrophysicians will measure it amongst the stars even. The expansion of the universe will slow down, pandas will breed in captivity and all soldiers will cry, lay down their weapons and hug.
+Herr Hansen lol damn
this was back when I was a fb conspiracy person :P Times have changed
***** This is good.
Question everything! But always keep both feet firmly on the ground.
Jiggling mess is my constant state too. I feel ya, methane.
why is no one talking about the fact we just watched a murder and someone being burned alive 0:14
But I want to ask something we are taught are mass can be converted into energy so how is energy conserved?
Awsome Ted - Ed more like Today ❤- Education ❤
That's pretty cool guys
so the energy transfer is always 1 to 1? it never loses some energy in the trade?
What about entropy? I thought that always meant energy gets weaker evereytime it's transferred to a different type of energy?
Oh my god this guy. "or your vegetables" *rolls eyes*
veganss.. he didnt forget abt the vegans!🍆🍆😂😂
jass movie pH 15
I'm still laughing at that
Does this simplified explanation not then lend itself to a notion of temperature not being possible without particles, vis a vis a true vacuum, even in regard to photons.
Lurve the isometric CG illustrations
0:27 This is not true. The total amount of energy in the universe is not constant, because energy conservation is replaced with a more complicated general relativity analog.
2:09 not true, because it's very rare that air temperature is higher than your skin temperature even in the summer, you feel hot because your energy production term holds your body heat over the ambient.
So you are not here to learn. Then why do people like u come to these type of videos?
Most of the energy in the universe is Dark Energy
nice
I have a question.
When I start running, i'm filling with energy. But if i hit a wall, i'm going to lose this energy, into a bit of heat, but the rest of the energy is gonna be lost right??does it mean that the whole universe just lost some energy?? The laws of thermodynamics says that energy can't be created, so every time there's a collision, The whole universe loses energy it can't produce. The universe would then some day run out of energy??
Anyone please explain what is the reason for feeling cold. Feeling hot during the day can be understood as heat released by collision of more energetic air molecules with the skin. But what about the reason for feeling cold?
actually what we feel as cold temperature is just what you feel due to the energy lost from your body...your temperature or the entropy of your molecules is higher that that of the air surrounding you thus energy is transfered from you straight to the atmosphere...and that is what you feel as cold
barba thomas it reminds me two things - tesla words and religious words...
Practically poetry~
4 days in biophys, still confused
4 minutes in this video, I get it!
I love this video. I watched robots have a seizure, the video suggest we blow up ourselves at our next cookout, thanos snapped that corn, and the other one was absolutely consumed
But from where does the energy first arouse in the universe,what's the source
good
Kinetic Energy(K.E.) is mother of all energies. K. E. requires motion. Space is in perpetual motion. Space is made of virtual particles. All energy comes from space.
Do protons not warm you up even a little? Or do we not feel the warm from protons at all and their just basiccly almost absorbed by the atmosphere.
Interesting.
the worst part is at 3:52, if you know what I mean.
Thanks ! Now I'm more educated than 4 minutes ago :)
same here, I saw this video today at my grade 9 Science class
But where does the initial energy come from? You assert it is there..but where does it come from?
Energy = Chameleon phoenix
Awesome
*Energía*
Explicado de la manera más simple posible :) Energía = el fénix camaleonido.
Tha was a fkin good one
The I have a fish reproduced to form another fish 1st came from I like this energy somewhere came from from the Big Bang from other part but it can be come from in the first place
This guy is such a chemist
Doesn't the fact that virtual particles exist violate the law that states the sum of energy in the universe is constant?
I'm not sure if this is correct, but I think it doesn't, because virtual particles exterminate each other too fast to be meaningful (I think it has something to do with plank's time), so the conservation of energy is not violated. But I may be very wrong
nachoijp You are correct, when two virtual particles spawn from fluctuations in the quantum foam they almost always nearly instantly annihilate with zero net. But there is one exception when a pair spawns straddling a black hole where one side lies on the event horizon and another is in normal space the black hole will strip one away allowing a new energy.
Not if all particles are thaught of as virtual
Does it makes sense to think particles like that? virtual particles are just mathematical oddities, other kinds of particles are real
Why not, they would no longer be oddities either, it doesn't go against either relativity or quantum mechanics, and the concept would be used to explain both what we now consider virtual and real particles
Before big bang there was nothing. But where did the energy come to the universe?
Please explain the origin of energy 😞😖
The change in tone when the vegetable was mentioned could be viewed as negative.
Energy is very understandable
As far as i know... Energy isn't really conserved in a universal scale... It only stays same until we include time dilation and warps into the picture... For example around the blackholes... The existence of singularity causes massive time and space warps... Infact beyond the event horizon time simply stops relative to the outside world... So any energy that goes in... Is pretty much lost. We simply don't know what happens to it
lol
0:39 - Wait… ARE THOSE MO FROM WALL-E?
I thought the same exact thing!
@@abigailtangonan4034 Same!
(why am i replying to a 3 yr old comment...)
They do look like MO to me
Is that the reason why you can see air vibrating when it's really hot?
is this from a video game, I have a desire to play this
Even a stretched rubber band is kinetic energy because all things are in constant motion even when appearing still, by way of particle structure ....even , light energy . Otherwise the BB could never have happened !
Perfect vid!
If Universe is expanding, energy inside the universe is not constant.
no when universe expands energy inside is used in expansion transforming into different subjects when it shrinks energy again transform into previous state and again bigbang occurs
The concept that universe is a giant bubble is wrong! There is no defined boundary of the universe.
But of course there is that whole over expanding universe problem. The net energy stays the same but the space to have it in expands to a point where energy too spread apart for life to exist as we know it.
Awwwwww
That energy, neither created nor destroyed, but ever shape-shifting; the chameleon-phoenix of our physical world.
Is it just me or those little robots look like Claptraps? =P
Is that Brian Clough speaking ?
Poor lady was severely burned by that grill.
What if everything is being created in the now & entropy is what the now is building upon & the razor sharp moment we call now is sharper the smallest particle and all energy is being created from nothing on the smallest scale in the now? Then a black hole would be a place of higher concentration of creation? Just a thought.
Huh, Energy is apparently Burn-E from Wall-E.
really???
i want one of these robot dudes as a pet...
Very informative but does answer the question :where does energy come from
E=mc2
All of the energy in the universe is ... zero, right?
MOAR robots!
This doesn’t explain where energy comes from though!
She has eyebrows now!
hmmm.... So, what exactly is a kamehameha?
When the universe expends, background radiation shifts from x ray to radio wave. Where does the energy go?
Ok so this barley gives an indication of what a scientist would call average translational kinetic energy.
😮
Misleading title!
what if there are so much of us that the energy that its transmitted to the universe get bigger and bigger creating destruction?
