Asatellite orbiting earth once per day. from the reference frame of the moon, which orbit earth once about every 27 days, what is its motion?

a. the satellite never moves relative to the moon
b. the satellite travels continuously away from the moon.
c. the satellite remains at a constant distance from the moon.
d. the satellite continuously move closer and farther away from the mood.

If each day the satelite orbits the earth its going faster than the moon and is passing it, so the satellite continuously moves closer and further away from the moon. like if you were standing watching a race then the racers would be moving away then towards you then away again

Would like to . could you translate to english

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
