The principle of the reference system Keyword: reference system, the principle of space, the principle of relativity, split, the same meters: Chinese Wu Xing Guang吴兴广 Reference system used to describe the motion of the object, as a reference system for the description of the same object for different moving objects, motion state may differ. Why objects moving objects as a reference system described the movement of an object may be different? Reference system is equal, which is not also equal performance? Reference Department describe what is the standard of the sport? The role of the reference system is the same? Description of the different reference systems of the same object is equivalent to it? The following is taken from the "spatial awareness" Stationary object exists in the space; object moves, the object exists in the space. Thereby know the contents of the presence of the space with the objects still or moving. We can describe the spatial stationary or moving objects. We know that 1) in the stationary and the moving coordinate one meter and one meter of space is the same. 2) the stationary and the moving coordinate 1 m and 1 m of space is different. 1) that a, stationary 1-meter-long objects on the athletic department or a meter, is as long as one meter interval of space. describe the principle of relativity space is the athletic department and the rest frame of the same 'space moving objects in the rest frame of 1 meter per second 1 second after the space of one meter each to the same' in the athletic department 1 second to 1 meter per second movement of objects through space of 1 m 1 m and 1 m of the same .2) said is a motion of 1 m in the motion system, in the stationary opinion than 1 m. How can we explain this nature? The description of the different reference systems when space is different, we described the space it? The space is composed by a point in the space, with respect to the moment in time. In the reference system, we are through the point in the space to describe the space. For example, 10 meters away from the reference system, means that the space on the point; 11 meters, the space point. The point on the space interval is the size of the space (in the athletic department or in the rest frame) interval of 10 meters and 11 meters from the place is one meter. This description reference system is the movement or stationary unrelated. Still is to stay in the space of the object point (no movement) to another point. Movement must through the space that is to say, in the space of different points. When only one object (shape negligible), we can not describe the space more points, and only when two or more objects, in order to determine the different points in the space of two or more, in order to show the different space , in order to show the space interval. The two objects (stationary), to display a space interval between two objects; to see the movement of objects through the different points of space a stationary, a movement, a stationary object, the moving object to see the stationary object, the stationary object in motion, after different points in space. The space interval between the two described. (For example, AB = BA), both describe the same space (or description) said different angles of space. As a reference system, a moving object from space seems is in the rest frame of one point to another point, interval per second through space to the point description of space space. Absolute rest is fixed point absolutely stay in space. The representatives of absolute rest is on the point of absolute space, see absolutely still, absolutely still, but also the movement of moving objects, so it makes no sense to say absolutely still. Two relative motion of objects, no matter in which an object is in the state (including the absolute rest), appears to motion in another object, space interval between each other. Referred to as the movement of reciprocity. (Said space reciprocity or) Through the above description, we know that the the stationary space described the space described by the athletic department are the same space, but the description of the different perspectives, both interchangeable relationship. (This is a 2) of said meters and 1 meter different) For a different description of the space (reference system), can not change the size of the space. 1-meter-long object stationary in the athletic department or a meter long, or one meter of space occupied. The objects in the stationary (with respect to the stationary) movement after one meter space, and the motion in the motion system after one meter space is the same. Space by a point in the space, the space described by a point in space. How to describe the point of the space? Reference system to a point in space, or to a designated space on the reference system. So that due to the different state of motion of the reference system, caused by a different description of the space. The reference frame is equal (the principle of relativity), in any reference system for describing spatial spot on the space, the size of the space is the same, i.e. the movement 1 m of the reference system with respect to space in the motion system and stationary relative the movement 1 meter space in the reference system is the same. The state of motion of the reference frame different, resulting in the description of the space different, this difference can be mutually converted. Space description of the athletic department, in the rest frame appears to the athletic department per second through space as zero. Replaced by the speed of this relationship is the classic law of velocity composition. (Here, a different reference frame time is the same, see "the essence of time origin of the time") Stationary DPS zero through space to a point in space, motion based DPS through the space v m (v. .1 seconds = V m) to indicate the point in the space, then in the motion system to speed v1 movement of objects in the rest frame seems is (v + v1) meters of space per second (said one of the cases). With the speed that is the classic speed synthesis. Different reference systems on the description of the spatial location of the object are equivalent, are objects described position in space, regardless of where a reference-based or the same angle described. Not only a relative sense, we usually refer to but both absolute sense. Space is uniform, differing only from different angles on a description of the space. Any point in space is not moving. ---- Use Dividing the angle of view to describe the spatial reference system is, the space of the motion-based, a point on the space is a space segment, stationary opinion can also be divided in the sports department own opinion, called the space segment of the stationary, that is, space point; athletic department seems space is composed by these space points, points in space is a space that can not be further divided. The athletic department to see the rest frame of the space point is the so-called stationary subdivision of space, the so-called stationary points in space is the space segment. Based on movement reciprocity, we can see that both described in the same space, the same space. Seen as a reference system for different moving objects are in a different space segment to describe the same space as a point in space. Space is no different, but described a different angle. Equal performance of the reference system is the reference system is a fixed point, different reference systems in the one meter and one meter is the same, different spatial reference system is the same. Different reference systems where space is the same, the experiments made also. When we described using a reference system the movement of the object in the another reference system, that is, the original description of two different angles of space is converted into the description of an angle to the space. Such a course of one meter between the different reference systems different with one meter space size and space, or space and space (here, the space refers to the space described by the reference system).
