  • i really want to watch this video..... but theres this video on the left with a chick with a nice ass called "lose yourself"....

  • 47:42 : "and then, if I feel very good, I will do that again" - priceless face

  • Can someone help explain the concept of where a volt comes from? I did my best to follow his explanation but when he started doing all the math and everything else I lost it. Just a conceptual understanding is what I'm asking cause right now that's a huge block in my way to moving onto other E&M concepts. Thanks

  • This video is a favorite on Tbilisi

  • hiya ich bin total naja wie soll ich sagen reich

  • @dimpubeckylu Lift an object of mass m a height h above the ground. The work done by you, in lifting that object will be mgh, where g = gravitational acceleration. This is more intuitive to us. Once you match gravity, all you need to do is be just, just stronger.

  • Thank you Walter Lewin! Voltage was presented to me very vaguely and as a concept I should accept on face value, I appreciate it being explained from first principles and then named at the end of the process. That is real teaching.

  • @dimpubeckylu The charge is pushing back Walter. Therefore he has to do work to overcome this. The force he needs to overcome the charge is arbitrarily greater than the charge's force. If you make an analogy with gravity, it is easier.

  • genius@@

  • lol...Walter Lewin force F WL
