12: Simple Harmonic Motion
- #10The energy of system in simple harmonic motion is given by
E=12m ω2A2.Which of the following two statements is more appropriate?
(A) The energy is increased because the amplitude is increased.
(B) The amplitude is increased because the energy is increased.Ans : Statement A is more appropriate because the energy of a system in simple harmonic motion is given by `` E=\frac{1}{2}m{\omega }^{2}{A}^{2}.``
If the mass (m) and angular frequency (ω) are made constant, Energy (E) becomes proportional to the square of amplitude (A2).
i.e. E ∝ A2
Therefore, according to the relation, energy increases as the amplitude increases.
