In general a trajectory is any path between two points although intermediate points should be given to describe complex trajectories. Hence in the context of a DVE, a trajectory is created by a series of Keyframe s which have been defined by the operator.
(n.) The vertically curved path taken by a bullet after it leaves the barrel of a gun. If you draw an imaginary straight line exactly parallel to the center of the bore, the bullet will fall away from that line.
In general, the path in three dimensions (i.e. space) of a moving body. The word trajectory is often used to mean flight path. If the trajectory is a closed path around another object like the earth, the trajectory is called an orbit. When the path is not closed, the word trajectory is usually used.
A term used to describe the flight characteristics of a golf shot. Trajectory describes not just the direction of a shot (hook, draw, straight, fade or slice) but also considers the height of the shot as well as it's launch and landing characteristics.
The path a bullet takes in flight. A flat trajectory refers to a path the curve of which was modified by the high velocity of the projectile. The more rapidly the projectile moves, the less the trajectory will curve, although an absolutely flat trajectory can not be achieved.
The trajectory of a sprinkler is the measurement (in degrees) of the angle of the water projecting out from the sprinkler’s nozzle. A trajectory of 0° would indicate a flat projection of water out from the nozzle.
the angle at which the ball comes off the clubhead. For today's low spin balls higher trajectories are more desirable in drivers. Yet many game improvement irons tend to launch at higher angles which may not be desirable to advanced players who want more control.
