Electric field definition | Electric charge, field, and potential | Physics | Khan Academy

In this video David explains why physicists came up with the idea of the electric field, how it's useful, and explains how the electric field is defined. Created by David SantoPietro.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

whoever this narrator is is solid gold! You make things easier and easy to follow. Thank

[zalasyu]

Totally got it after watching this video. I didn't quite understand reading from my textbook or viewing other info. videos. Excellent work!!! Please keep it up!

[muheeproductions]

khan academy is the best education channel in YouTube

I couldn't understand the concept until this video, man deserves a raise

"Are we just making up stories to make ourselves feel better here?"

HAHAHAHAHA

This video demonstrates the value of philosophy. Logical-philosophical thinking can help solve some of the biggest problems in science. The idea of an electric field is a great example of philosophical abductive reasoning or "inference to the best explanation". (1) We observed the phenomena of charges repelling each other. (2) We asked "How do charges exert a force on each other without coming in contact?" (3) We developed a hypothesis, "electric fields", which best explained the phenomena we observed. This hypothesis explains the phenomena well and works out with the math better than other possible hypotheses. As such, the electric field hypothesis will tentatively be thought of as "real" until something else explains the data within greater explanatory scope, explanatory power, and is less ad-hoc, etc.

Great explanation. An excellent example of a 10-15 min video explaining physical concepts - laid back attitude, a short historical background of the problem, repeating the most important ideas multiple times and keeping it to the point.

[eshwarray]

Excellent. You have not thrown some formulas on is, but you have explained how these formulas came up. Thank you very much

[feelingzhakkaas]

excellent explanation in very simple ... god bless you sir.

[omargrisha]

Best one explaining the concept of electric field

[stellahstars]

Very well explained, I have been struggling with this topic for 2 years now. Thank you so much. 🙏🙏🙏

[blchitu]

Please do more, you deserve more subscriber's this world need guys like you

[medic]

how could i thank you...
you are amazing, and you explain it in a very easy way

[xbxndgx]

I like the graphics and it's really easy to understand :D

[JawHacks]

absolutely fantastic video. thank you.

[khashiaawaheed]

Superb explanation..Understood really well and helped me in making notes!

[mariamel-nazer]

I have a crush on your understanding of physics and your very facile way of explaining it. This made my day, it made me feel like there's still hope for the complex concepts I abhorred as a highschooler(and consequently dropped). Thank you so much for your hard work!

[bhuvi]

Really loved the definition of electric field @9:00 ! Thank you so much :)

[jianmao]

thanks very much, my professor can only teach us with phisics language which we can not understand.

[nguyengiang]

Wow i love this explanation! Thank you!
