Question

Name the property by virtue of which an object resists a change in its state of rest or of uniform motion. Also, name the physical quantity which is a measure of this property.

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.
