Motion

=**motion**=

In phisics, motion is a change in position of an object with respect to time. motion is bacicly descriped in terms of velocity ,acelleration, displacement and time. motion is observed by attaching a frame of reference to a body and measuring change in position relative to another reference frame. a body which does not move is said to be at rest or to have a constant position. an objects motion can not change unless acted by a force, as described as newtons first law. an objects momentum is directly related to the objects velocity and mass,and the total momentum of all objects in a closed system (one that does not change to external forces) does not change the time, as described by the law of conservation of momentum.in physics of motion ,in the universe is described through two seats of apparently condradictory laws of mechanics. motion of all large scale and familar objects in the universe (such as projectiles ,planets, cells and humans ) are discriped by classical mecanics.whereas the motion of very small atomic and sub atomic objects is descriped by quantem mechanics. In the United States there is a law, a **motion** is a procedural device to bring a Limited, contested issue before a court for decision. A motion may be thought of as a request to the judge (or judges) to make a decision about the case. Motions may be made at any point in administrative, criminal or civil proceedings, although that right is reguLated by court rules which vary From pLace to place. The party requesting the motion may be called the //movant//, or may simply be the //moving party//. the party opposLng the motion is the //nonmovant// or //nonmoving party//.
