  • Graaaaaaaaavaaatational 2:29 :P

  • @narutolynx Work is also any type of energy, so it can be A=W :)

  • 2 people cant Do physics for their life

  • Could someone tell me if the potential kinetic energy of the top 15 floors of the WTC was a sufficient amount to turn all the concrete to dust, and turn the whole pile into nothing but rubble?

    How would you figure out how much KE would be needed to pulverize the concrete and pretty much everything else?

  • egg litering

  • @YetziroVenni 1st convert ft to meters

    Ep=mgh

    Ep=1000 (9.8) (meters) sin40 J

  • These equations are all good and stuff but the real questions is how far off are we from converting those equations into a working gravitational engine...that is the real question and trumps any question that has and will be asked

  • way cool video, thanks

  • thanks man

  • THANK YOU SO MUCH.. (: i have a report on this..and you sir saved me..thank you so much
