# trajectory

«trajectory» in Mova's school dictionary: **the curved path that a thrown, kicked or fired object…** — its meaning for a pupil, its sense in the lessons and examples.

### part of speech

noun (a trajectory, trajectories)

### meaning for a pupil

1) A trajectory is the curved path that a thrown, kicked or fired object follows through the air or space. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/T/trajectory/#m1)

2) A trajectory is also the direction in which something develops over time, like the trajectory of a career or of prices. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/T/trajectory/#m2)

### sense in the lessons

In science and maths it is the path of a ball, arrow or rocket, usually an arch shape called a parabola because gravity pulls it down. In space lessons rockets and probes follow trajectories to planets. In grown-up talk: «on an upward trajectory» means getting better or bigger. Phrases: «the ball's trajectory», «change trajectory», «on a trajectory».

### note

Countable; plural «trajectories» (y → ies). Stress on «-JEC-». A trajectory is a path, not a speed. A thrown ball's path is a curve (a parabola), not a straight line, because gravity pulls it down all the time.
