The Dimension of displacement is an important concept to consider when discussing forced migration. To fully understand the impact of displacement, it is necessary to understand the different ways in which it can occur.
There are three primary dimensions of displacement: spatial, temporal, and functional.
Spatial displacement refers to the relocation of a population from one geographic location to another. This can be in an entirely different geographical location or a neighboring area within the same country/state/region. It is multifaceted in its effects and can have a large impact on the lives of individuals who experience it.
Temporal displacement is the separation of a population from their traditional homeland or way of life over an extended period. This can be due to conflict, natural disasters, or other factors that cause people to flee their homes. It can also refer to the forced assimilation of a group into a new culture or society.
Functional displacement occurs when people are forced to leave their homes but are unable to do so due to factors such as a lack of security or access to resources. This can lead to internal displacement, where people are forced to flee their homes but remain within their own country. It can also lead to cross-border displacement, where people are forced to leave their country and seek refuge in another.
Each of these dimensions can have a devastating impact on the lives of those who experience it. It is important to understand them to fully appreciate the scale and scope of displacement around the world.
Dimensional Formula of Displacement
Firstly, always keep in mind that dimensions are written based on units of quantities. In the case of displacement, it is meter, then its Dimension is expressed using a formula. The Dimensional Formula of Displacement = M0L1T0.
The SI unit of displacement is measured in meter (m). Displacement of a dimension is typically described as the change in the position of the particle in a particular direction during a specified time interval.
What is the Dimension of Displacement?
Dimensions of Displacement are a vector quantity, and it only has the unit of length. It can be represented in the metric system or imperial system. Dimensional displacement tends to be in a straight line, the shortest distance between two points.
Displacement is the distance typically between two positions, which is a length value. It could also be linked with two sets of coordinates as required. However, in the case of no displacement where the beginning and ending positions are the same, we only have a position. Remember that a position is also contemplated as a unit of length and it is associated with only one set coordinate.
Dimensions of Velocity
Velocity is a rate, you might already know. The unit of Velocity is displacement over time. But, the distance traveled in a path that is NOT in a linear pattern (a straight line) over a course of time is called speed (instead of Velocity). Speed is also defined as a rate.
Dimensional Formula of Velocity
The Dimension of Velocity is described as displacement divided by the time taken in the displacement covered. It is considered as a vector quantity.
Dimension of Velocity Formula = [M0 L T-1] or L/T
V represents Velocity
L represents the length (unit measured in meters)
T represents time (unit measured in seconds)
Magnitude in Displacement
Magnitude in displacement indicates the size of the displacement, NOT in terms of its direction (i.e., just a number with a unit).
For example, a driver standing in front of his/her car could move back and forth as many times, perhaps walking a distance of 100 meters, still end up only 5 meters to the left of their starting point.
Distance traveled can be greater than the magnitude of the displacement.
One way to think about the Dimension of displacement is to presume you marked the start of the motion and the end of the motion.
Ignoring to include a negative sign, if needed, will cost you a wrong answer for displacement.
Let's see what the solved examples involving displacement look like.
Example1: Displacement of 4 Moving Objects
Four objects move as per the paths in the figure shown below. Suppose that the units of the horizontal scale are provided in meters. Calculate the displacement of each object?
Object 'A' had a primary position of 0m and an ultimate position of 7m. The displacement of object 'A' can be expressed using this equation:
Δx A= 7m − 0 m
Object 'A' had a primary position of 12 and an ultimate position of 7. The displacement of object 'B' can be expressed using this equation:
Δx B= 7m − 12 m
= -5 m
Object 'C' had a primary position of 2m and an ultimate position of 10m. The displacement of object 'C' can be expressed using this equation:
Δx C= 10m − 2 m
= +8 m
Object' D' had a primary position of 9 and an ultimate position of 5m. The displacement of object 'D' can be expressed using this equation:
Δx D= 5m − 9 m
Hence, the dimensional displacements of 4 objects are 7, -5, 8, -4m, respectively.
Example 2: Distance Traveled from Four Moving Objects
Four objects move as per the paths given in the figure. Suppose that the units of the horizontal scale are provided in meters. Calculate the distance covered by each object.
According to the figure shown,
Object 'A' traveled a total distance of 7m
Object 'B' traveled a total distance of 5m
Object ‘C’ traveled a total distance of 8m + 2m+2m = 12m
Object D traveled a total distance of 6m + 2m = 8m
We can see from these examples that displacement refers to the distance traveled from a starting point, not including the direction of travel. We use the unit 'meters' for its measurement, and it is considered as a vector quantity.
The magnitude in displacement indicates the size of displacement NOT in terms of its direction (i.e., just a number). A driver standing in front of his/her car could move back and forth as many times, perhaps walking a distance of 100 meters, still end up only 5 meters to the left of their starting point.
Displacement is measured by finding the difference between the starting point and the endpoint of the motion. If we were to include the negative sign in the equation, it would indicate a displacement in the opposite direction. When solving displacement problems, be sure to include the negative sign if needed.
