Trajectory

Portions of this entry contributed by Kringle Daly

A trajectory is the path followed by a projectile.

In ballistics, the easiest way to describe a trajectory is by its x- and z-components, with the z component being affected by local gravity. Ignoring air resistance, a particle that is fired from the origin at time t = 0, where is the initial velocity and is the initial angle made with the x-axis, the trajectory of a particle is described by

where t is the elapsed time and g is the gravitational acceleration, and its velocity components are
