Is there a unit for the size of the displacement, and how can the displacement be compared to the si

Displacement A directed segment that points from the initial position to the final position.

Displacement is a vector quantity, with magnitude and direction.

The unit of displacement is the unit of length. In the International System of Units, the unit of displacement is "meter".

The magnitude of the displacement, which is a positive number (including units).

If moving in a straight line, the displacement can be indicated by plus or minus signs. For example, if the object is moving in a straight line in the east-west direction, if the orientation to the east is the positive direction, the displacement is s1 2 meters (indicating that the direction is east), and s2 3 meters (indicating that the direction is west), and the comparison of the magnitude of these two displacements is s1 s2 (the absolute value represents the magnitude).

There are units of displacement, and the unit is not necessarily meters, and other units of length are fine.

The magnitude of the displacement can be positive or negative, for example, if the right is positive, then the left displacement is negative.

Displacement is a vector quantity that has both magnitude and direction. There are positive and negative directions, and magnitude is measured in numerical units. The displacement is united, and the SI unit is generally taken as "meter".

There are sizes, there are units, there are positive and negative. Units look at the distance of the unit. Hope you are useful!

Yes, but not necessarily rice. Displacement also has a direction, and where there is a direction, there is a positive or negative.

Yes, the size should also have units, and there is no positive or negative size.

Positive and negative represent the direction, the premise is the positive direction, the SI unit is m, and only the magnitude is an absolute value, that is, a positive number.

The numerical fit unit refers to the amount of displacement, and positive and negative indicates the direction in which the displacement moves relative to the positive direction.

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 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.

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).

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.

First of all, the formula x=x2-x1 requires that two of them be known, for example: x1 represents the initial displacement, and x2 represents the final displacement. The variable that is found is the change in displacement.

Displacement is a vector quantity, when the vector is represented by numbers, the absolute value of the number is used to represent the size, as long as an object has a displacement, its size must be a positive number, so the displacement of the ball should be used as an absolute value, and 2 meters will be obtained. -5 is the resultant displacement, which is the addition of -2 and 3. A method in which positive and negative signs indicate direction, the displacement is positive when the direction of the displacement is the same as the initially defined positive direction, otherwise it is negative.

The difference between displacement and displacement magnitude is: displacement is a vector quantity, which has both magnitude and direction; Whereas, the magnitude of the displacement is a scalar quantity, and only the magnitude has no direction.

The displacement of the car is a directed line segment from the initial position to the last position, and if a to b is taken as the positive direction, the displacement is +200 meters, and + means that it is the same as the specified positive direction.

The displacement magnitude is 200 meters.

Displacement is a loss, there is a magnitude and a direction, and the magnitude is the distance from the end of the object to the initial position of the object; The direction is the direction of the arrow from the initial position to the last position. The magnitude of the displacement is scalar, only the magnitude has no direction. Its magnitude is equal to the magnitude of the displacement.

Distance, on the other hand, is a scalar quantity, with magnitude but no direction, and its magnitude is greater than or equal to the magnitude of displacement.

1. No, the displacement can be found in that way. It is used on the condition that the direction of acceleration is constant. That is, linear motion in the same direction.

2. In this example, the distance is the sum of the lengths of each section. Displacement refers to the length of a directed line segment drawn from the beginning to the end position and the arrow pointing.

3. The displacement from the end to the beginning is found. The symbol indicates the direction from the end to the beginning.

The displacement represents the change in the position of an object (particle). It is a directed segment from the beginning to the end of the position, and its size is independent of the path, and the direction is from the beginning to the end point. It is a physical quantity with magnitude and direction, i.e., a vector.

Take a look at these two diagrams.

In the problem of the ball, the default upward is positive here. The magnitude of the displacement refers to the absolute value of the displacement, the displacement has a direction, while the magnitude of the displacement has no direction. An analogy can be drawn here between a vector and its modulo length.

The minus sign of 5 represents direction.

When an object is moving, a directed line segment that points from the initial position to the end position is a vector, that is, directional. It's not the same as the distance.

It is loss, and the magnitude is the length of the straight line relative to the original position, and the direction is from the original position to the last position.

The horizontal distance, displacement, and distance passed over a period of time are different, and the displacement emphasizes the horizontal distance, while the distance emphasizes the actual distance.

A segment with a opposite direction where the initial position points to the end position.
