why motion of the moon around the earth is periodic but not oscillatory?
Answers
Motion of a particle can be simple harmonic(SHM) if there exist a centralized force which is proportional to its displacement from center (directed towards center). But in case of earth there exist a centralized force that acts towards center (sun) but it is proportional to inverse of square of the displacement between earth and sun thats why motion can't be SHM.
here's ur answer.....
