The trajectory is the journey of a body through space.
From the French trajectoire , the trajectory is the path described by an object that moves through space. A bullet propelled by a weapon, for example, describes a trajectory, which can be traced or assumed by a specialist.
For mechanics , the trajectory is equivalent to the successive geometric places that a body occupies while it moves. Its determination depends on the place from which the observation is made.
The trajectory of a body is, generally, a line that enjoys continuity. There are exceptions, such as the case of an orbital electron that occupies different positions in an atom . In these cases, the trajectory is probabilistic.
Trajectory types
It is possible to distinguish between various types of trajectories. The rectilinear path occurs when the movement is one-dimensional and can be reduced to a straight line. The curvilinear trajectory , on the other hand, resembles a curve with continuity and can be three-dimensional or two-dimensional. The erratic trajectory , finally, takes place when the mobilization is unpredictable and the geometric shape becomes irregular.
A ball kicked by a soccer player traces a trajectory.
In the case of this last type of trajectory, it is worth highlighting the fact that under this name is what is known as Brownian movement, which is defined as being that random type of movement carried out by the particles found in what is a fluid. . This name was established as a way to pay tribute to the Scottish biologist Robert Brown who was the one who in the first decades of the 19th century, more specifically in 1827, discovered that aforementioned phenomenon.
The concept in meteorology
It is important to highlight the fact that the term trajectory is also used in the field of Meteorology. In this specific case, it is used to refer to the course followed by various environmental phenomena such as a rotating storm or a hurricane.
Thus, for example, this year the specialized services in this scientific field have allowed us to be informed at all times of the path followed by Atlantic hurricanes such as Oscar, Florence, Gordon, Kirk or Nadine. And the same has happened with impetuous winds originating in the Pacific area, such as Aletta, Norman, Carlota or Fabio.
Personal and professional career
The trajectory, on the other hand, is the direction that the behavior of an individual, a group or an entity takes over time. Professional career is often used to refer to the different jobs that someone does in their life.
For example: “Real Madrid has incorporated a forward with extensive experience in the NBA” , “The governor's career is impeccable: any accusation that comes from the opposition will be dismissed in minutes” , “An actor with little experience surprised the press by claiming an Oscar Award.”
In this case, it is common to talk about what is known as personal and professional career. Two terms that are used, for example, when preparing a resume because they encompass the studies and courses completed as well as the jobs that have been held so far. The first case would correspond to the aforementioned personal sphere while the second would be the professional one.
