Question

Ronit has two solid blocks of same size and shape made of steel and plastic.Which one of the two has highest inertia.Give reasons for your choice.

Answer 1

Answer:

Since, steel has more density than plastic and wood. So, its mass will be greater and hence it will have greater value of inertia, as inertia of a body is measured by the mass of the body. Heavier the body, greater is the force required to change its state and hence, greater is its inertia.

Answer 2

Answer:

Well my name is Ronit.

The steel block is denser and hence has more mass than plastic box of same volume.

Since mass is a measure of inertia the steel block will have more inertia.
