MCQ
A pendulum is oscillating on either side of its rest position. The correct statement is : ________ .
  • A
    It has only the kinetic energy at its each position.
  • B
    It has the maximum kinetic energy at its extreme position.
  • C
    It has the maximum potential energy at its mean position.
  • ✓
    The sum of its kinetic and potential energy remains constant throughout the motion.
✓

Answer

Correct option: D.
The sum of its kinetic and potential energy remains constant throughout the motion.
The sum of its kinetic and potential energy remains constant throughout the motion.
Hint: In accordance with law of conservation of mechanical energy, whenever there is an interchange between the potential energy and kinetic energy, the total mechanical energy remains constant.
