+== Trajectory ==
-== Definition ==
+A '''trajectory''' is the path that a moving object follows through space as a function of time. It is often associated with the motion of projectiles, such as bullets, balls, or any object that is thrown, shot, or propelled. The study of trajectories is a fundamental aspect of [[physics]] and [[engineering]], particularly in the fields of [[ballistics]] and [[aerodynamics]].
-== Mathematical Description ==
+== Physics of Trajectories ==
-== Trajectories in Astronomy ==
+The trajectory of an object is determined by the initial velocity, the angle of launch, and the forces acting on the object, such as [[gravity]] and [[air resistance]]. In a vacuum, the only force acting on a projectile is gravity, which causes the object to follow a parabolic path. This is known as [[projectile motion]].

-In [[engineering]], the term trajectory can refer to the path taken by a vehicle, missile, or other moving body in space. Engineers often need to calculate the optimal trajectory for a vehicle to reach a certain destination.

'''Trajectory''' refers to the path that an object follows through space as a function of time. The concept is used in a variety of fields, including [[physics]], [[mathematics]], [[astronomy]], and [[engineering]].

== Definition ==
In [[physics]], a '''trajectory''' is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite, for example. It could also be a particle moving under the influence of particular forces, such as gravity.

== Mathematical Description ==
In [[mathematics]], a trajectory is a sequence of values of a dynamical system. In a discrete dynamical system, the trajectory is a sequence of real numbers, while in a continuous dynamical system, it is a continuous function of time.

== Trajectories in Astronomy ==
In [[astronomy]], the trajectory of a celestial body refers to its path around a center of gravity. For example, the trajectory of the Earth around the Sun is an ellipse.

== Trajectories in Engineering ==
In [[engineering]], the term trajectory can refer to the path taken by a vehicle, missile, or other moving body in space. Engineers often need to calculate the optimal trajectory for a vehicle to reach a certain destination.
