Trajectory
path of a moving object / From Wikipedia, the free encyclopedia
The Trajectory something follows is its path through space and time. If a cannon is fired, its shell will follow a certain path depending on how much gunpowder was used, how heavy the shell is, and the angle up and down that the cannon is aimed at.
