Campaign recognizes - movement is poor

Keywords: sports, sports, space, absolute rest reference system Author: Wu Xing Guang (吴兴广)China(中国)

Object with respect to a change of position of the other objects is called a mechanical movement, referred to as motion. The movement of the size or speed of movement available speed.

Two moving objects, the comparison of the magnitude of the motion, the speed difference is available. Example, object A speed V1, the speed of the object B as V2, the magnitude of the motion of the two objects of the comparison is the speed differential of the two objects, that is V1-V2. The difference between the speed of the 'for comparison to the size of the object motion of the two movements, but also can be called a motion difference. The speed difference or sport differential is a comparison of the size of the two objects movement. The speed difference (or said motion difference) related to the speed of the two objects, any one of the two objects, the object's speed changes, the motion difference will change. We found that the speed difference of the two objects is a velocity value, that is V1-V2 = V. We usually the object with respect to a change of position of the other object is called motion, describing the motion of an object with another object, as a standard, visible we usually the size of said one object's speed is the speed difference of the two objects, i.e. the motion difference.

The size of a speed of an object is a description of the movement size, is described in the state of motion of an object; described motion difference is the difference between the state of motion of the two objects.

When an object's state of motion, due to the inertia of the object, the object has not been external forces, the state of motion remains unchanged, that is the same speed (including the size of the speed). Movement differential is the difference between the state of motion of the two objects, related to the state of motion of the two objects, as long as there is a changed state of movement of objects, the motion difference will change. Movement difference V1-V2 = V, we can use the V represents the movement. 'Sport' and 'the motion of an object the size of' in V, is likely to cause confusion between the two. We usually refer to the speed of an object's size is the movement of the two objects. The displacement of the movement of the object, that is, the differential displacement of the two objects. Displacement difference is displacement, denoted by S. Displacement can be described as the movement of objects through space, then the displacement difference is the space between two objects change, two objects change size. []

Why is the movement of an object, the movement of two objects becomes worse? Because the motion of an object relative to another object, while the other object is also the movement.

Moving objects, as well as when the shift by the force. Such as accelerated motion. Comparison of a stationary object with accelerating objects count is not the comparison of the state of motion? Accelerate acceleration of an object is relative to another object that, I think this movement is also a difference between a. So that the concept of 'sport differential' we usually refer to the speed and acceleration. Motion difference refers to the comparison of any of the two movements.

Comparison of absolute stillness and movement of objects

Based on the reciprocity of the movement, a stationary object, a moving object, stationary objects moving objects seems also a movement. Including absolute Still.

Absolutely still relatively stationary or difference. A relatively stationary object as a reference system to describe the movement of another object, that is, we usually say that a constant speed or variable-speed movement, not caused by the motion of an object; absolutely still as a reference system to describe the movement of another object, the size of the movement are the motion of another object.

Movement reciprocity difference is actually moving reciprocity. Absolutely still relatively stationary object as a reference, although the movement of the two objects are described, but the absolute difference stationary object with another object movement is due to the movement of another object caused. A relatively stationary object with another object of the motion difference is caused due to the joint movement of the two objects.

Poor movement of change is absolutely stationary objects and other objects of the sport differential change is due to a change in the movement of another object. The relatively stationary object and the difference between the change in movement of another object, it may be relatively stationary object movement occurs changes that result, it may be another change the motion of the object caused by two objects movement changes caused .

Absolute rest is absolutely fixed in space. The absolute stationary object does not exist, is absolutely fixed objects in space does not exist, the movement of objects in space is absolute. General movement is absolute, it is relative to space said.

All objects are in space. In the space, there are two types: 1) a description of the object, all objects with respect to the description of the space. How relative to the space to describe it? Absolutely still absolutely fixed objects in space, all objects relative to the movement of the space is relative to the movement of absolute rest frame. The movement of all objects have a relative speed values ​​for absolute rest frame, called a absolute motion, absolute speed. 2) of all objects in space can be mutually described, the movement is described with respect to the movement of the reference system, and we called a relative movement. This results in a magnitude of the motion is a motion difference between the objects. Just like the movement of the object within the reference frame can not prove whether the reference frame motion, the movement of the reference system or not regardless of the movement of the object in the reference system, (all of the objects are in the movement of all the objects in the space) space can not prove that the space of the motion or not, the movement of the space or not, does not affect the movement of all objects in the space. (I think the space is fixed.)

The description of the object in space as in the reference system. In the reference frame, 1) all objects can be described with reference system, all of the object relative to a reference system has a certain value, can be called the 'absolute speed' relative frame of reference; 2) reference system the object can be mutually described. Object with respect to the other motion of the object referred to as a relative movement. Although the absolute stationary object does not exist, but do not affect the mutual description of all the objects in the space.

The role of the reference system is a description of the state of motion, although the description of the different reference systems of the same movement, but can not change the state of motion of the object reference system, force is the reason to change the state of motion of the object.

Reference system of a role as the spatial coordinates, all objects have the space coordinates expressed describe the motion of the object with the reference system of coordinates. Movement of all objects can be included in this coordinate utterly description the movement unified description of all objects. So that you can compare the difference between the movement of objects. Between the objects in the reference department has been able to compare with each other or description, it is because they have a unified spatial coordinates in the space of a unified, however described, the difference in movement between the objects is constant.

The movement and the relationship of the reference system as the relationship of the gravitational potential and the reference plane, select a different reference frame, the movement size value is different, it does not affect the movement of the study. 1 because of the issues related to determine the significance of the difference of the motion, this difference does not select a different reference is different.

In fact, we had been involved in the comparison of the state of motion of the two objects, here the difference between the state of motion of the two objects, referred to the movement. The key is that we usually call an object's movement is exercise. Such an object the size of the motion of the object becomes the problem of the motion difference of the two objects; motion change by itself unstressed object becomes the two objects is not one of the object by the force of the object; objects moving through space becomes two objects space interval change.

The motion difference of the two objects can be viewed as the movement of an object relative to another object.

Only due to poor movement of change with no force, regardless of the reference frame, reference system does not affect the size of the movement is poor. The reference system is different, the same movement is poor. So the difference between the total amount of movement between objects unchanged. For example, the movement of objects A, B, C of the three line B on the left on the right, C, A in the midst. The motion difference of the objects B and A is V1, the motion difference of the the W objects A and C is V2, V3 objects B and C are motion difference. Motion difference with the object A, object B and A and C of the total amount of motion difference B and C is equal to the object movement, V3 = V1 + V2 'motion of an object' movement difference is the speed of synthesis, synthesis of classic speed.

An object with respect to the movement of another object, that is, the change of the spacing of the space between two objects. The change of the spacing of the reference system selection of the space does not have effects, therefore, equal to the total amount of space interval changes between objects. (Spatial interval variation is usually we speak of displacement.) For example, the objects A, B, C of the three original at one point, then movement in a line, B on the left on the right, C, A in the midst. Opinion the object A, AB is the object A, B spatial interval variation; AC is the object A, C spatial interval variation. Object B opinion, BA is the object B, A space interval variation; BC is the object B, C the spatial interval variation. Opinion the object C, CB is the object B, C between spatial interval variation; CA is the object A, C between spatial interval variation. Because no effect of the change of the spacing of the choice of the reference system space, AB = BA, CA, = AC CB = BC. Opinion, the object A, the total amount of the other two objects change is AB + AC opinion, the object B, the total amount of the other two objects change BC; the object C, the total of the other two changes in object space Cover is CB. because the choice of the reference system has no effect on the change of the space interval, so the object B opinion, BA unchanged, AC unchanged, so BC = BA + AC.t Similarly, CB = CA + AB.

Therefore, the total amount of space between objects change BC = BA + AC = CA + AB = CB.

Poor movement changes with force. The force is the change of the state of motion of the object, the difference changes the movement of two objects, must be a strong role in one of the objects. [2]

The object exists in the space, the movement is the movement of the object in space. Only the space interval between two objects is changed, we say that the object (with respect to reference system) is in motion. The change of the spacing of the space is to determine the amount of movement of the object. If the space interval does not change, we can say that the object does not have a (relative) movement. The space (interval) of the change is to determine the standard of the movement of the object.

Related to the magnitude of the difference of the speed of movement of the spatial interval variation is determined by the size of the motion difference.
