Question

mention briefly about the two states 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 two state of motion are contact and non contact
