It means that the object is moving.
if its velocity is increasing or decreasing
In common terms, that means that it is moving.
the object is not moving
That is the object's 'speed'.
when can you say that the object is in motion
You would say that the object in motion is accelerating. Or you can say that the object's velocity is increasing.
It means that the object is moving.
It means that the object is moving.
An object in motion will stay in motion, at a constant velocity. This assumes that no net force acts on the object. This is known as Newton's First Law.
when it change in position or in place
if its velocity is increasing or decreasing
In common terms, that means that it is moving.
when it change in position or in place
That is equivalent to saying that:* The object moves, or * The object's position changes over time
the object is not moving
That is equivalent to saying that: * The object is moving, or * The object doesn't stay all the time in the same place.
