Trajectory meaning: A trajectory or flight path is

A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously. The meaning of TRAJECTORY is the curve that a body (such as a planet or comet in its orbit or a rocket) describes in space. How to use trajectory in a sentence. Trajectory definition: the curve described by a projectile, rocket, or the like in its flight.. See examples of TRAJECTORY used in a sentence. Did you know? Formed with part of the prefix trans-, "across", trajectory means a "hurling across". By calculating the effect of gravity and other forces, the trajectory of an object launched into space at a known speed can be computed precisely. Missiles stand a chance of hitting their target only if their trajectory has been plotted accurately.
