World's Most Asked Questions: What Is Energy?

What is Energy? The short answer is EVERYTHING. But what does that mean? Let SciShow explain.

Really the world's most asked question: "Are we there yet?"

[VomicaEmanio]

SciShow Hey Hank, I'm not quite satisfied with that answer. If I'm to describe why I see the answer as "incomplete" then I'd say this: I ask you what makes up water and you say Molecules when I wanted to hear Oxygen/Hydrogen (or even better, quarks and that sort of stuff).
In short: Yes, energy is everything, it makes up everything, but what IS it? All matter around us is made up of quarks and gluons and stuff and there's a lot of information about what exactly those things are. You could probably spend an hour telling me everything about quarks, why not spend like 5 minutes telling me about energy? It's like, if the question had been "what is matter", you'd have just answered "it is quarks". Tell a bit more detailed please, this is one of the questions I've been curious about for quite some time and I just can't seem to find an answer anywhere

"lungs absorbing oxygen..."
Great. Now I'm breathing manually.

Was expecting an answer but he just reiterated what we all learned in primary school.

''Everything is energy
and energy is you and me''

It's Log, Log, Log! It's Log, Log, it's big, it's heavy, it's wood. It's Log, Log, it's better than bad, it's good!

Watched this in science class today. Totally made my day.

So, does this mean every time I fart, I'm farting out a star?

[edmundangles]

I think it would be worth mentioning Noether's Theorem in this context. That energy is the constant that must exist if the laws of universe are constant in time. I think that is quite profound:)

You can tell how much Hank loves his energy.

my teacher made me watch this i watched the first 20 seconds and then asked her if there was an english version

[Random-eihf]

Who's here becuase their teachers made them watch this?

[TheDoomAmbassador]

Follow up question, could you expand upon how matter is energy?

[stellart]

when i saw your tv commercial on the tv I squealed so much that my mom turned around and looked at me as if i had grown a second nose

This may help some people who found this video useless.

There are two kinds of energy. The first kind, which is talked about in this video, is not made of anything. It is simple a term used to describe a trait of matter. Things like potential and kinetic energy are not real, physical objects they are mathematical concepts that describe properties of matter. However, the second kind of energy does exist physically as light.

Light is made of photons, which are little bundles of pure energy. The more energy something has, the hotter it is, the faster it moves and the more light (energy) it radiates. The Sun has an enormous amount of energy and blasts the Earth with its radiation. Radiation is a physical wave of energy that travels at the speed of light. They come in all kinds of different frequencies which are determined by how much energy the wave has. These waves of radiation are what we see as light. The light we can see is only a small portion of the full spectrum of light. The spectrum goes from gamma rays (which are extremely powerful waves of energy that would destroy the human body) to x-ray, ultra violet, visible light, infrared, microwave, and finally radio.

So to actually answer the question of "what is Energy?" There are two meanings to the word. One is a mathematical concept that describe attributes and traits of matter. Like Kinetic, potential and chemical energies. The other is a physical particle known as a photon which radiates from all matter and we perceive as light.

How thought provoking and awakening. All of us are connected with the energy that's been here through the starting of universe.

Can I just say I freaking love the comment sections here!
Scrolled down for almost an hour just reading people asking questions, other people (mostly nicely) answering them, or starting intellectual debates that don't end up being about each others mums. Hats off to all of you =D

*There is no space, time, matter, or energy. This constitutes a topological transformation.* -- *Alexander Vilenkin*

[Kazishairslikesoradd]

this was more of a description of energy rather than an ontological explanation of what energy "is" in its essence. but maybe only im asking for that version of the question...
