Question

There are three solids made up of aluminium, steel and wood of the same shape and same volume. Which of them would have the highest inertia and why?

Answer 1

Answer:

steal will have more inertia becoz of its mass

Answer 2

Dear Student,

◆ Answer -

Steel

● Explanation -

We know,

density(steel) > density(aluminium) > density(wood)

As the solids are of same shape and volume, their mass will be directly proportional to density.

Hence, mass(steel) > mass(aluminium) > mass(wood).

As inertia is directly related to mass of the body,

inertia(steel) > inertia(aluminium) > inertia(wood)

Therefore, steel body will have highest inertia.

Thanks dear. Hope this helps you...
