Question

A body executes simple harmonic motion. The potential energy (PE), kinetic energy (KE) and total energy (TE) are measured as a function of displacement y. Which of the following statements is true?

• A. TE is zero when $ x=0 $
• B. PE is maximum when $ x=0 $
• C. KE is maximum when $ x=0 $
• D. KE is maximum when $ x $ is maximum

Answer 1

Answer: (C)

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