BPSC – Combined Competitive Examination · வினா 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
விடையைக் காட்டு & விளக்கம்

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

விளக்கம்

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

  • (A) தவறு

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

  • (B) சரி

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

  • (C) தவறு

    Wrong: meaningless; gravity is what causes the fall.

  • (D) தவறு

    Wrong: irrelevant to the energy question asked.
