Question

State the relationship between mass and inertia

Answer 1

Mass and Inertia are probably the same thing.

In other words, Inertia is directly linked to the objects mass.

Newton’s first law clearly explains about Inertia that is “An body at rest wants to be at rest while an body in motion wants to be in motion’.

This tendency of the body to be in rest or resist the change in its position is termed as inertia.

Example: You are given a massive rock whose mass is about 100 kg and a small rock about 10 kg, both the rocks are at rest and you are assigned a work to move them to a certain place.

Now, which rock do you think moves easily.

10 kg (small rock ) isn't it.

Since small rock has less mass, its inertia is less that is it offers less resistance when someone applies force while large rock offer more resistance to change its original position of rest to motion due to its mass.
