Question

What is inertia? What is a measure of inertia? State its si unit?

Answer 1

Inertia is the ability of a n object by which it resists the change in current state of motion or state of rest.

Mass.is the measure of inertia.

Its S.I. unit is kilogram.

Answer 2

Answer:

Inertia is the inherent property of a body to resist the change in its natural state of rest or motion .

There are three types of inertia :

Inertia of motion

Inertia of direction

Inertia of rest

Inertia of motion :

The  inherent property of a body to resist the change in its natural state of

motion is inertia of motion .

Ex : When the bus suddenly comes to a halt , we tend to fall forward . This

is due to inertia of motion .

Inertia of rest :

The  inherent property of a body to resist the change in its natural state of

rest is called as inertia of rest .

Ex : When a bus suddenly comes into motion , we tend to fall backward .

This is due to inertia of rest .

Inertia of direction :

The inherent property of a body to resist the change in its current direction

of motion .

Ex : When a bus suddenly takes a turn , we tend to move in the outward

direction . This is due to inertia of direction .
