What is Energy REALLY?!

Ever wonder what energy really is? Me too... join me on a journey of discovery (kinda).

Him explaining why we don't know what energy is, gave me a better understading of energy then any book I've ever read...

[JoakimfromAnka]

Finally an honest video on this subject.

[hanx]

I recently got really carried away with watching your videos, running out of new ones so gone back to the old ones you've done and it's interesting how you've changed over the years. Honestly some of the best videos I've ever seen, I really really appreciate every single hour you put into making these videos. Stay crazy!

Almost all science sources explain what energy does. This is my attempt at explaining what it IS.

Great work condensing all energy into two forms everyone understands (potential and kinetic) and then using relativity to show that they're one and the same. I know people who take college-level physics struggling to make sense of the concept of energy. I find it funny that it took me so long to figure out what you've explained in a 4 minute video. Hope this gets more views!

I like this guy's no bs approach.  +1 sub

[phxbillcee]

You're a nut, but an informative nut! I don't always follow totally, but you give me something to grab on to & think about. (Only have 2 yrs of college, no physics & am mostly self-taught since {I'm 62 now}). I try to keep up with what we "know" currently, but that can be somewhat slippery, depending on how divisive the current schools of thought are in a subject. I really appreciate your channel, &, please, keep up the good work!

I'm really glad i found your channel, none of other ytbers can't share knowledge with such a simplicity, passion and humour. You sir deserve way more subscribers

[jeffrobertson]

The answer to what is energy is really pretty simple. Energy is the capability of something to undergo a change. It’s not a fluid, it’s not a substance. It’s just a number and a very useful number. But like mass, momentum, and velocity, it’s a number that can only have value in relation to something else.

I've always been intrigued by this work. Energy. We know so much about it, yet we do not know what it truly is. Even though it will always be something incomprehensible, your video has given me a lot of clarity on the topic, and now I am less confused by the whole concept lol. Thank you.

[srijansingh]

This person is just making me love science more and more❤️

[kochenk]

I've always felt the way we define what energy is to be so weird. I'm glad I'm not the only one who feel this way.

Finally something that makes sense of the types

[pidodvy]

I love how the video starts. The visualization of a person bumping around and acting "a little crazy" is a common misconception amongst kids about energy, thus associating the lack of energy as being tired. That's a great epistemological obstacle when teaching the more abstract concepts of potential and kinetic energy.

"You gotta use your mind's eye" woah dude.

Thank you!!!! Your video is the best of all the "what is energy" vids bc your the ONLY one who actually admits we dont really know what it even is or how to define it! Before watching your video I was thinking energy was some physical thing- I kinda had like a clear sphere in my imagination lol- now your making me realize I wanna say energy is actually the behavior of the thing, similar to a wave- a wave isnt the thing itself, a wave is the way the thing is behaving or moving... does that make any sense??.... correct me if Im talkin crazy...

[livvielov]

Really good video a little bit disappointed that we don't actually know, though

[MrWildbill]

I think both the unknown and our inability to describe many things, like energy in terms of "what it actually is" makes physics so compelling to me. The "whys" are pretty cool also, why energy acts like it does, why after the big bang all of that energy did not just continue to radiate forever as photons, why did it take the form of matter in the first place. If it makes your head hurt thinking about it too long then you are probably on the right path :)

[sgtsnakeeyes]

thanks, this was exactly what I was looking for.

[seastormsinger]

I just gotta say, aside from loving your videos for their content, I love love love the little grammatical corrections you throw in. They make me very happy.
