In the physical sphere, mobile is understood as the object in motion from which one wishes to study its trajectory or the forces that accompany it.
This concept has a special interest in dynamics and kinematics, given that the object of the study is precisely a mobile object. In order to simplify its study, sometimes the mobile is reduced to a theoretical point where the whole mass is concentrated and on which the forces intervene and which moves within a system. If this simplification is not made and the mobile is a three-dimensional object, we can also consider studying rotation movements on its center of gravity.
