During a training session, two footballers pass a ball repeatedly between each other. The 'to and fro' motion of the ball is not simple harmonic because the
I. Acceleration of the ball is not directed towards a fixed point
II. Restoring force is not directed towards the centre
III. Acceleration of the ball is not directly proportional to the displacement from a fixed point
Which of the statements above are correct?
I and III only
I and II only
II and III only
I, II and III
Correct answer is A
In SHM, the body must have acceleration in a direction opposite to the displacement and the acceleration must be directly proportional to displacement. Also, the acceleration must be directed towards its mean position. This is not the case with a football on the pitch.
