      sorry to be so off topic but does anyone know of a way to get back into an instagram account?
      I stupidly forgot the account password. I love any assistance you can give me!

      @Wilson Isaias i really appreciate your reply. I got to the site on google and Im in the hacking process now.
      Takes a while so I will get back to you later when my account password hopefully is recovered.

    At around 8:40 I'm confused wouldn't the mass of whatever is being attracted have an affect?

    • @boss8177
      @boss8177 5 років тому +9

      it wouldnt because it would cancel out. Remember mg=GMm/R^2 so the little m cancels out.

      Gravity is a "two way street", so yes, both objects involved would be attracted to each other. However, as long as M is much larger than m, you can neglect the motion of M, and focus only on the motion of m. When m is much smaller than M, the acceleration of m is independent of mass, since both gravitational mass and inertial mass come as a package deal. So the orbital mechanics are independent of the mass of the body in orbit, as long as it is insignificant compared to the parent body that hosts the orbit.

    The (2s)^2 is written incorrectly because when multiplied it gives 4s^2 and not 2s^2

    • @Poopiroopi
      @Poopiroopi 6 років тому +5

      he divided 4s^2/2r so it cancels the 4 to a 2
