Častá chyba:
Learners sometimes use "trajectory" only for physical movement, like a ball in the air. In modern English it is very common for abstract development, especially with "career trajectory", "growth trajectory", or "life trajectory". Another mistake is to say *"trajectory of career"* instead of the natural collocation "career trajectory" or "the trajectory of his career".

Synonyma
course (Very close in meaning, but more general; used for paths, actions, and development, not as strongly linked to long-term change as "trajectory".)
|
path (More everyday and concrete; can sound less formal and less focused on long-term development than "trajectory".)
Antonyma
stagnation (Describes a lack of movement or development, the opposite of following a changing trajectory over time.)

Častá chyba:
Learners may confuse "trajectory" with simple words like "direction" or "way". "Direction" is where something is pointing; "trajectory" is the whole path it follows over time, often curved. Another mistake is using it for moving people in a place (e.g. *"my trajectory to school"*); in that case, "route" or "way" is more natural.

Synonyma
path (A more general and everyday word for the route something follows; it does not suggest a scientific or calculated curve as strongly as "trajectory".)
|
flight path (Commonly used for planes and birds; similar idea, but less general for all moving objects and less technical than "trajectory".)
Antonyma
standstill (If an object is at a standstill, it is not moving and therefore has no trajectory.)

Definice
The line or curve that a moving object follows through the air or space.
The curved path that a moving object, such as a ball, bullet, or spacecraft, follows through the air or space under the influence of forces like gravity and air resistance.

Častá chyba:
Learners may try to use this highly technical sense in everyday situations. In daily English, the non-technical senses (development over time, physical path of objects) are usually better. This technical meaning is mainly used in academic or professional texts in math, physics, and engineering.

Synonyma
orbit (In dynamical systems, "orbit" can describe a similar idea, but it may stress repeating or closed paths more than "trajectory".)
Antonyma
equilibrium (An equilibrium is a state that does not change over time, the opposite of following a changing trajectory through state-space.)

Definice
In science and math, the line that shows how a system's state changes over time in a diagram or model.
In mathematics, physics, and engineering, the curve that represents how the state of a system changes over time within a state-space or phase-space.
