Question

Considering a plastic ball and a stone of the same size, which among the statement is right.

• A. The plastic ball has more inertia than stone.
• B. They will not have any inertia.
• C. Both of them have same inertia.
• D. The stone has more inertia than the ball.

Answer 1

The correct option is D The stone has more inertia than the ball.

Inertia is the tendency of all objects to resist any change in state of rest or motion. Mass is a measure of inertia. More the mass, more is the inertia. Mass of a stone is more than the mass of a platic ball of the same size. Hence, inertia of the stone is greater than that of the plastic ball.
