Question

Name the physical quantity that measures inertia. State its SI unit.

Answer 1

1. The inherent property of an object due to which it resists any change in its state of rest or of uniform motion in a straight line by itself is called inertia.
2. The inertia of a body is measured by its mass.
3. The heavier a body, the greater is the force required to change its state and the greater is its inertia and vice versa.
