    The inertia of a moving object depends on

    A) momentum of the object

    B) speed of the object

    C) mass of the object

    D) shape of the object

    Correct Answer: C

    Solution :

    [c] For example, a cricket ball has more inertia because it has more mass (it is quite heavy).
    On the other hand, a rubber ball has less inertia because it has less mass (it is light).
    Thus, the inertia of the object depends on its mass.
