    Question

    A body is thrown vertically upward. The work done by

    gravity is: 
    A Positive Correct Answer Incorrect Answer
    B Negative Correct Answer Incorrect Answer
    C Zero Correct Answer Incorrect Answer
    D Infinite Correct Answer Incorrect Answer

    Solution

    When a body moves upward against gravity, the gravitational force acts downward while the displacement is upward. Since force and displacement are in opposite directions, the work done by gravity is negative. This negative work reduces the body’s kinetic energy as it rises.
