Question

please tell what is state of motion.

Answer 1

The state of motion of an object is defined by its velocity - the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity.

Answer 2

the state of motion is defined by its velocity- the speed with direction.
