Question

Which has highest inertia? Solids made up of aluminum, steel or wood of same shape and volume?

Answer 1

Step 1: Inertia

Inertia is the property of a body under which it opposes any agency that attempts to put it in motion or, if it is moving, change the magnitude or direction of its velocity.

Step 2: Finding the highest inertia

1. Here, given 3 solids made up of aluminum, steel, and wood.
2. As mass is the measure of inertia i.e. more mass, the greater the inertia.
3. Solid steel is having the greatest inertia.

Thus, steel has the greatest inertia.
