Question

It is easy to push an empty box at rest than the same box full of books, because:

• A. Empty box and box full of books have same inertia.
• B. Box full of books have less inertia.
• C. Empty box has more inertia.
• D. Empty box has less inertia.

Answer 1

The correct option is D Empty box has less inertia.

Inertia is the tendency of all objects to resist any change in state of rest or motion. Mass is a measure of inertia. It will be difficult to bring a change in state of the object having more mass. Hence it is easy to push an empty box than the box full of books.
