  • this is outstanding

  • email me at mellenstei@aol.com

  • so there is a centripetal force.... but why the water did not fall out...??

  • He talks like someone out of a Scooby Doo episode xD

    Great teacher though :D

  • Funny helps with kids. And he is funny. But if he is right, then Einstein is wrong. Think on that. Probably gravitation is a fictitious force appearing due to the deformation of space, and the only real force would be centrifugal. Accelerometers in free fall do not feel any force. That may be because it does not exist... (?)

  • And he IS freaking Chuck Norris !!!

  • struggling to understand physics...this helped ! Thx

  • Off topic I believe gyroscopic motion might be the link between mass and motion, and as you know, all existing matter is built upon complex rotating/orbiting motion.

    Even the Earth : )

  • I think this is a misconception of newton's law of acceleration. It only tells you what happens, it doesn't tell you why. It doesn't directly say that inertia is a force in its own right which acts on objects, though it clearly does, and no one dears to ask where that force comes from. I.e when you try to angularly accelerate a big wheel, you will feel an powerful resistance to your force, what is pushing against you?

    Even more troublesome are gyroscopic motion and forces.

  • He's wrong. The force pulling the ball outward is the centrifugal force caused by the ball's kinetic energy. Inertia.

    If there was only one pulling force, motion of the ball inward should have followed, but clearly another force is balancing that centripetal force. Science doesn't like this though for some reason...

  • @Nabo00o centrifugal force is a concept, but its just an simulation from inertia. he mentioned this in the video, there's not clearly another force.

  • thanks i get it now

  • Good demonstration and well presented.

    It amazes me just how many people think that there is an outward force, and frustrates me when they don't believe you when you tell them otherwise.

  • @ShadyMan01 I know, I just told my friend and he's all like "No dude. I think I'd know." and I say... "BUT I'VE PROVEN IT RIGHT IN FRONT OF YOUUUU!!!" I love how people will be in blind denial, even when you prove it.

  • this guy makes physics the best thing ever,at my uni all my physics teacher does is get dam equations and starts rearranging them to suite the question asked?i come to watch this excellent tutor to know why and what is happening? excellent thanks allot for uploading

  • he's good because he is CHUCK NORRIS

  • my 8th grade science teacher knew him :) i bet my science treacher was hands down the best teacher in amrerica other this this man

  • My physics teacher sucked all he said was wjat goes up comes back down >_>

  • I wish I had a physics teacher like him when I was still in school (sigh).

  • How did it become inertia?

  • This is by far the best explanation of the difference between centripetal force and centrifugal pseudo-force I have seen. Cut and dry, plain as day, simple as it can get.

    Avatar, it always was inertia (as soon as it started moving) - it didn't change into inertia when he let it go. When he let it go, the centripetal force was removed, and the ball simply continues on in the direction it was going immediately before being let go.

  • Thanks for posting.  Helped me so much:)

  • he is sooooooo funny. he makes physics fun!

    Even if you are not taking his course!

  • me to :) we watch his videos in class alot i love him!!!!!!!!!!

  • thanks. i'll try to put more on.

  • plzz put more i love poul hewwit

  • @mellenstei upload the complete lectures or where can I find them ?

  • Hahah, damn, I love this guy. I wish all teachers were as funny as him!
