Question

On what factors does the inertia of a body depend? Which has more inertia, an empty tin or a tin of the same size filled with sand?

Answer 1

Inertia:

1. Inertia of a body may be defined as, the property of a body to resist any change in its state of rest or of uniform motion in a straight line is called its inertia.
2. From our common experience, we know that it is easier to move a small and light object than a large and heavy one.
3. Thus, a heavier body has more inertia than a lighter body. Therefore, we can say that “the larger the mass, the larger is the inertia, and the smaller the mass, the smaller is inertia.”
4. In other words, we can say that "the mass of a body is a measure of its inertia."

Hence a tin of the same size filled with sand will have more inertia.
