      So you are qualified for bsc without clarity on gravitational equation.
      Great now I can see india as a super power.
      Please dont mind bro, I am not judging you right now even I am not a science student I just read it because I like it but you can also see that this is horrific.

    Sir, I have a question here. You considered here that v is the velocity and velocity = 2πr/Time. But, velocity = Displacement/Time and 2πr isn't the displacement. So, why
    v = 2πr/T here?

    sir i am a student of class 10... this is not really me. actually we both are here in front of the laptop screen and while watching your video we have found a question that if both the objects apply same force of attraction or lets say gravitation then why the smaller object revolve around the bigger object? I mean to ask why they dont stay stable in the universe?

    • @edupoint.secondary
      @edupoint.secondary  3 роки тому +7

      Consider two masses, one big and one small.
      If revolution happens, it is not correct to say that the small revolves around the big.
      Reality is - both revolve around the common centre of mass. This centre of mass resides very close to the centre of the big mass, so we don't see it's revolution.
