How do you compare the displacement to the size? How to look at the size of the displacement

The displacement should be compared to the magnitude to find themAbsolute，|x1|=3,|x2|=5.So |x1|<|x2|。

Generally speaking, vectors are only comparable in size in the same direction, and vectors in different directions generally cannot be compared in size. The summary of vector laws is based on people's understanding of the symmetry of space in a generalized sense. The symmetry (invariance) of translation and rotation on which vectors are based is valid for all the laws discovered so far.

The vector analysis method is used, which is called mathematical analysis.

This method is extremely creative and inspires physics research.

If an object moves from the initial position to the last position in a certain period of time, the directed line segment from the initial position to the last position is called the displacement. Its magnitude is the straight-line distance from the initial position to the last position of the moving object; The direction is from the beginning position to the last position. The displacement is only related to the beginning and end position of the object's motion, not the trajectory of the motion.

If the particle returns to its original position after a period of time during motion, then the distance is not zero and the displacement is zero.

x=x2-x1 (last position minus initial position), displacement is a straight-line distance, not a distance. In the International System of Units.

si), the principal unit of displacement is: meters. In addition: centimeters, kilometers, etc. The displacement formula of uniform velocity motion is x=v0t+1 2·at.

One object moved 3 meters in one direction and another 5 meters in the opposite direction.

Two numbers can only illustrate this. The displacement is a vector, including distance and direction, so there is no question of size.

Can it solve your problem?

The higher the number, the higher, and the plus or minus sign just indicates the direction.

The displacement is a vector, it has a magnitude, it has a direction, it can be positive, it can be negative, and it can be 0is the straight-line distance that connects the end and start points.

A directed segment where the start point points to the end point. It is a vector quantity, with a magnitude and direction, its size is only related to the beginning and end position, and has nothing to do with the intermediate process.

For example: s=v. AT can be used to obtain uniform acceleration motion.

displacement. When doing the problem, you should pay attention to don't forget to write the direction Run a lap in the playground, and after a lap, the person is still standing at the starting point, that is, the starting point and the end point are the same point, and the displacement is zero.

Displacement, English displacement, good mass refers to the change of position of an object or particle, which can be represented by a directed line segment connecting two positions successively. Suppose that the instantaneous T particle is located at the q point and the instantaneous T + T is located at the q point, then the vector represents the displacement of the particle in the T time interval from the T time.

It is equal to the difference between the sagittal diameter r(t+ t) of the q point and the sagittal r(t) of the q point, i.e., r=r(t+ t) r(t).

At the same time, the particle moves along the trajectory curve by the q point in the t time interval.

To Q, the distance traveled is arc long.

scalar). Therefore, displacement and distance are two different concepts. When t is small, the modulus and distance of the displacement vector are equal.

The direction of the directed line segment is the direction of displacement, and its length is the magnitude of the displacement.

Displacement is a directed line segment from the initial position to the final position, that is, a vector. Displacement uses displacement to represent the change in the position of an object (particle). Defined as:

A directed segment from the beginning to the end. Its size is independent of the path, and the direction is from the start point to the end point. It is a physical quantity with magnitude and direction, i.e., a vector.

The displacement is a vector quantity, and the displacement magnitude is a scalar quantity.

The magnitude of the displacement change is a vector change, and the change in the magnitude of the displacement is a scalar change.

For example, a particle moves 2 meters east to reach (2,0), and then moves 4 meters west to reach (-2,0).

The magnitude of the displacement change is 2-(-2)=4 meters, and the change of the displacement magnitude is 2-2=0, I hope it helps you.

<> displacement ratio is a numerical value in architectural jargon. The displacement ratio refers to the ratio of the maximum horizontal displacement and interstory displacement of the vertical members of the floor to the average displacement of the floor under the action of the specified horizontal force considering the accidental eccentricity.

The basic adjustment of the displacement ratio:

1. Program adjustment: SATWE program cannot be realized.

2. Structural adjustment: The eccentricity between the rigidity center and the center of mass of the structure can only be changed by adjusting the structural plane layout; Here's how to adjust it:

1) Since the displacement ratio is calculated under the assumption of rigid floor slab, the maximum horizontal displacement and interstory displacement of the structure often appear at the corners of the structure; Therefore, attention should be paid to adjusting the stiffness of the lateral force resistance member at the corresponding position of the outer part of the structure, and reducing the eccentricity between the rigid center of the structure and the center of mass. At the same time, in the design, the stiffness of the floor slab should be guaranteed in the structural measures.

2) For floors where the displacement ratio does not meet the requirements of the code, the node search function of the program can also be used to quickly find the node with the largest displacement in the "Simplified Diagram of the Reinforcement Components of Each Layer" in the "Analysis Result Graphic and Text Display" of SATWE, and strengthen the stiffness of the walls, columns and other components corresponding to the node. The node number is found in the "Satwe Displacement Output File". It is also possible to find the node with the smallest displacement to weaken its stiffness until the displacement ratio meets the requirements.

Displacement is the directed line segment from the beginning point to the end point of the object (the starting point points to the end point, like the ray in mathematics), the length of this directed line segment is the magnitude of the displacement, for example, if a person walks from A to B without any restrictions, he can have countless paths to go, and the length of each path is the distance, no matter which way he goes, the directed line segment from A to B is the only one, this is the displacement, but A to B and B to A are not the same thing, the direction of the arrow is different, that is, The direction of displacement is different, if A to B is positive, then the displacement from B to A is negative. But it doesn't matter if you go from A to B or from B to A, if you follow the same path, the journey is the same, which means that the journey has no direction. Therefore, the magnitude of the visible displacement is less than or equal to the size of the distance, and the magnitude of the displacement will only be equal to the distance when the object is moving in a unidirectional linear motion (at this time, only the magnitude is equal, not the same).

Direction of displacement: The direction of displacement is from the beginning of the motion (the start point of the motion you choose) to the end point of the motion (i.e., the point where the object is located at the end moment, there is only one starting point, and the end moment can be determined by the problem, corresponding to different time periods).

The magnitude of the displacement: the displacement is the directed line segment between the position of the beginning and the end of the object's motion, and the resistance is a vector displacement magnitude, which is the length of the line segment, which is a scalar quantity.

Location size, there is no concept of location "size".

The significance of displacement: displacement is the Changyuan judgment vector, that is, the particle from the three-dimensional space.

The change in position of a crack to another is called the displacement of the particle during this movement.

Displacement is a compulsory part of high school physics 1. Definition of Mingzhou bend displacement: A directed line segment from the initial position to the final position.

The agitated physical meaning of displacement: it represents a change in the position of an object (particle). Magnitude of displacement:

The length of the line segment between the beginning and end of the position. The direction of displacement: from the initial position to the last position.

Displacement is a vector, that is, it has both size and direction, which is the key!

Displacement: The displacement represents the high-nucleus change in the position of an object (particle). It is a directed line segment from the initial position to the last position, and its size is independent of the path, and the direction points from the beginning to the end. Leather do.
