Question

    Which of the following are the characteristics of an

    inelastic collision? I. Momentum is conserved. II. Total energy is conserved. III. Kinetic energy is conserved. IV. All the forces must be of conservative nature. Choose the correct answer:
    A Both III and IV Correct Answer Incorrect Answer
    B Both I and II Correct Answer Incorrect Answer
    C I, II and IV Correct Answer Incorrect Answer
    D Both II and IV Correct Answer Incorrect Answer

    Solution

    In an inelastic collision:

    • Momentum is always conserved.
    • Total energy (including kinetic and potential energy) is conserved.
    • Kinetic energy is not conserved because some energy is converted into heat, sound, or deformation.
    • Not all forces need to be conservative in nature.
    Thus, options I and II are correct.
