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. [1 Mark]

Answer 1

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.

Hence option (D) is correct. [1 Mark]
