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.

Man, your explanations are on point!
This video help me unimagineably to understand the magnitude of electric feild
Special thank to you, may the lord bless you
Best wishes from iran
simply beautifully explained, thank you
you deserve more credits. live long Prof. 😍😍
THANK YOU! SO HELPFUL
I wish you were my physics teacher right now, mine is horrible at explaining and just tells us to read the textbook, thank you
girls n guys, a beautiful thing to know, graph b/w r and E(electric field) is gonna be a rectangular hyperbola, as u see E is inversely proportional to r^2
thank you!! Really good explanation
Big thankssss
3:47 uh said Q1 is a point charge ... No Q2 is the point charge .btw nyc explanation surrr!!!
u mean we reckon with test charge which is always positive. so, it will be attracted if we hv negative charge n will be kept off if we got a positive charge as the main charge of which we hv to find thee electric field...ryt?
3:35
somebody please explain a brief summary Im just having hard time taking all this in
Sir but if the charge create force on another charge we can say it is accelerating it so it distance change so the force on that charge not constant EXPLAIN🤔
When you are doing the calculation of Electric-field, you are into account the distance of between the two charges. So you are calculating the field with the fixed distance between the two charges. The E=q/r2 or even the E=(q1xq2)/r2 says that E-field will be lower as there is more distance.
0:14 ain't Q2 having an electric field?or is that the 'test charge' whose presence doesn't affect the electric field due to the source charge Q1...if so,y didnt we hear that frm our prof
the test charge is "tiny" so it does not disrupt the electric field created by the source charge.
Why is that the 10x to the power of 9 changed to 6?
I like this guy a lot more
Sir why radially inwards if negative and outwards if positive charge
Because same charges repell and opposites attract each other
@@Dobetterlivebetter u mean we reckon with test charge which is always positive. so, it will be attracted if we hv negative charge n will be kept off if we got a positive charge as the main charge of which we hv to find thee electric field...ryt?
