Q10.17: which of the following statements concerning simple harmonic motion is false? a : a restoring force acts on an object in simple harmonic motion that is directed in the same direction as the object's displacement. b : a restoring force acts on the object that is proportional to the object's displacement from its equilibrium position. c : during simple harmonic motion, the net force on the object is zero when it is at its equilibrium position. d : the displacement versus time graph for an object in simple harmonic motion resembles the sine or cosine function. e : the amplitude of the motion of an object in simple harmonic motion is the maximum distance the object moves from its equilibrium position.
