[Sarah]

The curve which a body describes in space, as a planet or cometin its orbit, or stone thrown upward obliquely in the air.

[Sarah]

A trajectory is the path a moving object follows through space as a function of time.

In control theory a trajectory is a time-ordered set of states of a dynamical system (see e.g. Poincaré map). In discrete mathematics, a trajectory is a sequence (f^k(x))_{k \in \mathbb{N}} of values calculated by the iterated application of a mapping f to an element x of its source.

[Julian]

The path followed by a projectile flying or an object moving under the action of given forces.
