【Motion】 ,  【movement】 ,  【move】 ,  【locomotion】 ,  【stir】  mean the act or an instance of moving.

【Motion】 is the appropriate term in abstract use for the act or process of moving, without regard to what moves or is moved; in philosophical and aesthetic use it is an especially comprehensive term, for it may apply to manifestation of change or of changing not only from place to place, but from condition to condition, or from step to step in a progression.

Ordinarily, however, the term implies discernible physical moving.

【Movement】  usually implies definite regulated 【motion】 ; the term is used less often than  【motion】 to denote an abstraction, although it may be extended to denote a quality of representation in a work of art that suggests 【motion】 or a quality in literary work (as poetry) that suggests a definite rate of speed or progression (as in the meter, the rhythm, or the action).

In concrete use  【movement】  implies a passage, whether self-initiated or under guidance or compulsion, from place to place, from situation to situation, or from condition to condition; it may, in this sense, be used interchangeably with  【motion】 in the collective singular or in the plural.

【Movement】 also is frequently used for an instance of moving.

【Move】 is particularly likely to denote a beginning of a 【movement】   or to apply to a definite instance of moving or moving something from one place to another. The word may stress the notion of change and then is particularly applicable to a changing of one's abode or to a physical or figurative moving to attain an end or objective.

【Locomotion】 usually suggests travel especially by artificial means (as by boat, train, airplane, or automobile), but it may apply to natural means (as wings or legs).

【Stir】 applies to a 【motion】 or 【movement】 , often without an implication of changes of place or condition or of progress, that involves a not necessarily displeasing disturbance especially of what has been quiet or at rest or free from excitement, bustle, or agitation.
