Question

Two solids made up of aluminum and steel of the same shape and the same volume are there which of them would have the least inertia.

Answer 1

1. The inertia of a body is measured by its mass.
2. The heavier a body, the greater is the force required to change its state and the greater is its inertia and vice versa.
3. Given, that aluminum and iron have the same shape and volume but differ in their density.
4. Density of aluminum is less than that of iron, thus the mass of aluminum will be less.
5. Hence, aluminum will have lesser inertia.
