Question

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 statements 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

Answer 1

Answer: (A)

KE is maximum when x = 0

Answer 2

At $x=0$ , kinetic energy is maximum and potential energy is minimum.
