Question

    When a body falls

    freely
    A its PE is converted into KE Correct Answer Incorrect Answer
    B its KE is converted into PE Correct Answer Incorrect Answer
    C its mechanical energy is converted into heat energy Correct Answer Incorrect Answer
    D None of the above Correct Answer Incorrect Answer

    Solution

    When a body falls freely under gravity, its potential energy (PE) due to height is gradually converted into kinetic energy (KE) as it accelerates. The total mechanical energy (PE+KE) remains constant (neglecting air resistance) as per the law of conservation of energy.
