  • "Gravity Explained" , So what is explained now about gravity big head?

  • @1800levso are you serious?

  • air must be attached also to gravity because earth spins at 1800km per hour, if air was not attached to earth, air winds should be at least 1000kmph so wtf is going on, still I don't understand what is gravity? if earth is spinning counter clock, how about a plane traveling counter and another traveling clockwise, should one be flying faster than the other one? how is air pressure affecting us? ?????? maybe I'm just a dummy please help. what is gravity?

  • Well so Newton said gravity is a force, and Einstein said gravity is an acceleration.

    Both are right. Since Newton's formula.

    F=m*a ( Force is equal to mass multiplied by gravity )

    So yes, acceleration and mass together translate into Force

    You could also say Force and mass together translate into acceleration.

    Both are right.

  • Great video.
