By the relative motion of neighbour objects
An object is in motion if it changes position relative to a reference point. Motion is a relative quantity and is expressed in respect to the position of another object. Example: both a car and the Earth are moving (earth is revolving around the sun) but if we express the motion of the car in respect to the Earth, we say the car is moving relative to the Earth. At the same time the earth is moving relative to the sun.
motion
An object can be at rest relative to a second object whilst in motion relative to a third object.For example, if you sit still then relative to the Earth you are at rest. However the Earth is both spinning on its axis and travelling around the Sun, so relative to an observer in space you are in motion. Einstein showed us that all such concepts are relative.

relative motion
motion occurs when an object changes its position relative to a reference point.
An object's motion in relation to something else

Movement Occurs When an Object moves Relative to a Stationary Object
motion
When its position is changing relative to our position. Note: all motion is relative to something else.
Relative to any chosen reference point.
Motion it the change of an object over time relative to its reference point. that is called a reference point.
motion
This is called relative motion. Relative to your frame of reference, the object's motion appears unchanged, even though it's motion has actually changed.
