    A trajectory is the curved path something takes as it moves through space - a ball's trajectory through the air, or a rocket's trajectory into orbit. People also use it to talk about a person's career or life: 'her career trajectory has been impressive' means the direction and path her career has taken, usually upward. It's a word that pictures a path with direction and speed, not just a random position.

    軌跡、彈道;(事業等)發展路線
