BPSC – Combined Competitive Examination · ಪ್ರಶ್ನೆ 125

The potential energy of a freely falling body continuously decreases. Therefore:

  1. The principle of conservation of energy is violated
  2. The principle of conservation of energy is not violated
  3. Gravitational force is violated
  4. Gravitational force is not violated
ಉತ್ತರ ತೋರಿಸು ಮತ್ತು ವಿವರಣೆ

ಉತ್ತರ: (B) The principle of conservation of energy is not violated

ವಿವರಣೆ

As the body falls, potential energy converts to kinetic energy; total mechanical energy is conserved.

  • (A) ತಪ್ಪು

    Wrong: lost potential energy becomes kinetic energy, so energy is conserved.

  • (B) ಸರಿ

    Correct: PE + KE stays constant (ignoring air resistance).

  • (C) ತಪ್ಪು

    Wrong: meaningless; gravity is what causes the fall.

  • (D) ತಪ್ಪು

    Wrong: irrelevant to the energy question asked.
