| Although sales have remained stable at about 10,000 units a year, the coin-op business has been on a downward trajectory for years. |
| The ball's trajectory eventually led him to the Herschel Basin, a meteor impact crater, which is where he finally crash-landed. |
| You're probably better off experimenting with loft angles, low-spinning balls and longer tees to get the ideal trajectory. |
| By coming so close to earth, the gravitational field will alter its trajectory ever so slightly. |
| The trajectory was computationally unstable because, apparently, the spin label and its crowded binding site were not adequately equilibrated. |
| The rocket burn sent SpaceShipOne on a trajectory that sent it climbing for almost a minute after the engine shut down. |
