  • how sad, more people are interested in an idiot crying over britney spears than physics.

  • 700 views....that's unfortunate.

    This is a wonderful series. Thank you MIT!

  • These lectures are so good that I feel I'm cheating on my school tests :$

  • @troponinnutrition Now it's approaching 70,000 views!

  • @DeluxeWarPlaya check out the views now brah

  • @JONN3H UK and US universities have a different first year. In the US, irrespective of the degree everyone has to pass this class.

  • why is he teaching mechanics equivilant to M1/M2 of Heinnemans books. I thought he was a degree level teacher.

  • To explain the ruler trick at the end (think pivot point): First understand that when the two fingers are the same distance from the center, they are supporting the weight of the ruler equally. When one finger moves in closer, more weight is being distributed onto it, thus increasing friction (normal force X μk). This friction goes from kinetic to static. On the other finger, however, friction goes from static to kinetic and undergoes the same process until they both meet in the middle.

  • Thank you a lot for exam review lecture which help me to pass the exam of physics 1 at chulalongkorn university where the physics exam is not for a normal human being to take.....

  • You do not even have to clean your hands for that last experiment. You can even one finger wet (giving it more friction). When you are reaching the center with the finger that has the least friction almost all the weight will be resting on that finger and almost no weight on the highest friction finger. So you always end up in the middle.

    Damn did I just corrected a professor of MIT? :-)

    For the rest, 95% of this lecture is lost on me but I like to hear him talk, he's a great teacher.
