The amplitude of a system moving with simple harmonic motion is doubled. The total energy will then be
A) 4 times as large
B) 3 times as large
C) 2 times as large
D) the same as it was
E) half as much

Question

Quizplus · Accepted Answer

The total energy in simple harmonic motion is proportional to the square of the amplitude. Therefore, if the amplitude is doubled, the energy becomes 4 times as large.
