Question
Which of the following relationships between the acceleration a and the displacement x of a particle involve simple harmonic motion?
(a) a = 0.7x
(b) a = –200x2
(c) a = –10x
(d) a = 100x3
Solution
In Simple Harmonic Motion, acceleration a is related to displacement by the relation of the form,
a = -kx,
which is for relation (c).
a = -kx,
which is for relation (c).
