Q. A body executes simple harmonic motion. The potential energy (PE), the kinetic energy (KE) and total energy (TE) are measured as function of displacement $x$. Which of the following statement is true?
A) KE is maximum when $x$=0
B) TE is zero when $x$=0
C) KE is maximum when $x$ is maximum
D) PE is maximum when $x$=0
Explanation
(a) At $x = 0$, kinetic energy is maximum and potential energy is minimum.
