How is the state of motion of an object is described?

Answer»

Answer:

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.
