The path through state space taken by a system It is the sequence of states or path plotted against time Two general forms affect fitness, positive-sum and negative-sum
The solution to a dynamical system in forward and backward time passing through a specified initial condition
The trajectory of something such as a person's career is the course that it follows over time. a relentlessly upward career trajectory
The trajectory is the path along with an assignment of time--the time assigned to a point along the path denotes the time instant at which the object assumes the configuration associated with that point [3, p 221] The trajectory is a function of time that specifies the configuration of the vehicle at every instant in the interval [0,T], where 0 is the initial time and T is the final time We therefore have and [4, p 358]
A set of points (either 2-dimensional (geographic position), 3-dimensional (geographic + altitude) or 4-dimensional (geographic + altitude + time)) defining the planned route of an aircraft Sometimes a trajectory also includes the maximum allowable deviations from the given points In the 4-dimensional case this is more properly called a tube
n the curve the ball takes on its path from one player to another çƒè¿è¡Œçš„轨迹。
In general, the path traced by any body moving as a result of an externally applied force, considered in three dimensions Trajectory is sometimes used to mean flight path or orbit , but orbit usually means a closed path and trajectory , a path which is not closed
The curving path followed by a projectile from muzzle to target Guns fired their shot at higher velocities, at relatively flatter trajectories, while low-velocity mortars had high trajectories
