If a satellite travels at constant speed at all points in its orbit, then its path is
 
  1) a circle.
  2) an ellipse.
  3) a parabola.
 
  It travels at constant speed because
  4) the net force acting on the satellite is zero.
  5) it is characteristic for a satellite to travel at constant speed in this type of orbit.
  6) gravitational force decreases with increasing distance.
  7) there is no component of gravitational pull directed along the satellite's path.
  8) of inertia.

Question 2

A satellite in an elliptical orbit travels at a
 
  1) constant speed
  2) variable speed
  3) not enough information to say
 
  because
  4) the net force acting on it is zero.
  5) of the component of gravitational force existing in its direction of motion.
  6) it is characteristic of it to do so.
  7) again, not enough information is given to say.
