What does trajectory mean?
The trajectory of an object is the path it follows once in flight or in motion.
The word is especially used in the context of the path of projectiles like rockets, but it can be used in many different contexts.
The trajectory of a golf ball is the curved path it follows in the air after being hit by a golf club. The trajectory of an asteroid is the path it follows in space. The potential trajectory of a storm is the route that it may travel.
In geometry, trajectory is used in a more specific way to refer to a curve that intersects through a series of points at the same angle.
Example: Try to determine the trajectory of the ball as it flies through the air so you can position yourself to catch it.
Where does trajectory come from?
The first records of the word trajectory come from the 1660s. It comes from the Latin trājectōrius, meaning “casting over,” from the verb trāicere, “to cast” or “to throw over or across.” The first part of the word is equivalent to trans-, meaning “across,” and the root jec comes from the Latin verb jacere, meaning “to throw” (the same root forms the basis of motion-related words like projectile, eject, and many others).
Thanks to gravity, what goes up must come down. The path that something follows as it takes the journey up and then down again is its trajectory. When gravity is in play, objects that are thrown or propelled in some way follow a trajectory in the shape of what’s technically known as a parabola, which is basically a kind of curve. The word trajectory is commonly applied to the path of things that travel in this way, but it can be used more generally to simply refer to the route of something from one place to another, such as the trajectory of a storm. It can also be used in a more figurative way, as in career trajectory—meaning the path that one’s career has taken.
