The average energy in one time period in simple harmonic motion is(a)

1.	The average energy in one time period in simple harmonic motion is(a) 1/2mω2A2 (b) 1/4mω2A2(c) mω2A2 (d) zero.
Answer» (a) 1/2 m ω² A² EXPLANATION: The total energy at any instant in a simple harmonic motion is constant and equal to ½m⍵²A². Hence the average energy in one time period will also be the same = ½m⍵²A². So option (a).
