Апсолутно тврдо тело: Разлика помеѓу преработките

Според тоа, позицијата на апсолутното тврдо тело има две компоненти: '''линеарни''' и '''аголни''', соодветно.<ref>In general, the position of a point or particle is also known, in physics, as '''linear position''', as opposed to the '''angular position''' of a line, or line segment (e.g., in [//en.wikipedia.org/wiki/Circular_motion circular motion], the "radius" joining the rotating point with the center of rotation), or [//en.wikipedia.org/wiki/Basis_(linear_algebra) basis set], or [//en.wikipedia.org/wiki/Coordinate_system coordinate system].</ref> Истото важи и за други [[Кинематика|кинематички]] и [[Динамика (физика)|кинетички]] количини за опишување на движење на апсолутно тврдо тело, како што се линеарни и аголна [[брзина]], [[забрзување]], [[моментум]], [[Импулс (механика)|импулс]], импулс, и [[кинетичка енергија]].<ref>In [//en.wikipedia.org/wiki/Kinematics kinematics], ''linear'' means "along a straight or curved line" (the path of the particle in [//en.wikipedia.org/wiki/Space_(physics) space]). In [//en.wikipedia.org/wiki/Mathematics mathematics], however, [//en.wikipedia.org/wiki/Linear linear] has a different meaning. In both contexts, the word "linear" is related to the word "line". In mathematics, a [//en.wikipedia.org/wiki/Line_(geometry) line] is often defined as a straight [//en.wikipedia.org/wiki/Curve curve]. For those who adopt this definition, a [//en.wikipedia.org/wiki/Curve curve] can be straight, and curved lines are not supposed to exist. In [//en.wikipedia.org/wiki/Kinematics kinematics], the term ''line'' is used as a synonym of the term ''trajectory'', or ''path'' (namely, it has the same non-restricted meaning as that given, in mathematics, to the word ''curve''). In short, both straight and curved lines are supposed to exist. In kinematics and [//en.wikipedia.org/wiki/Dynamics_(physics) dynamics], the following words refer to the same non-restricted meaning of the term "line":
