newtonian mechanics - Satellite in Elliptical orbit


When finding the period of a satellite orbiting the earth we equate the centripetal force to the gravitational force


mv2r=GMmr2

If I understood well the r cancels into the r2 because the distance from the earth at any point on the orbit equals the radius of the orbit. Now what if we have an ellipse instead of a circle?


And by the way why does Kepler's 1st law say In elliptical orbits

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
