This is because the displacement would be zero as the satellite returns back to its starting position 11 View Full Answer V.manoj Preveen answered this when a satellite moves around the Earth along a circular path,then the force of gravity acts on it towards the centre.the force of gravity of the earth and the direction of movement of the satellite are perpendicular to each other.therefore W=FORCE(DISPLACEMENT)(Cos 90^{0}).therefore work done=0J. 54
