There are three solids made up of aluminium, steel and wood, of the same shape and same volume. Which of them would have highest inertia?
Inertia depends upon mass of an object. Since, steel has greatest density and greatest mass therefore, it has the highest inertia. It is given that all have the same volume therefore, the object with large volume will have more mass. We know that the density of the steel is greatest of all thus steel would have higher energy.
