Vedclass · Answer

(B) No,the motion of an artificial satellite in a circular orbit is not simple harmonic motion $(SHM)$.For a motion to be $SHM$,the restoring force must be directly proportional to the displacement from the mean position $(F = -kx)$.In the case of an artificial satellite,the gravitational force provides the necessary centripetal force $(F_c = \frac{mv^2}{r})$,which is constant in magnitude for a circular orbit.While the motion is periodic (it repeats itself after a fixed time interval),it lacks the linear restoring force characteristic required for $SHM$.

An artificial satellite is orbiting the Earth. Is its circular motion a simple harmonic motion?
