Trajectory

A trajectory is the curved path followed by an object moving through space, particularly under the influence of forces like gravity, propulsion, or wind resistance. It represents the object's progression in terms of position over time. The shape of the trajectory is determined by factors such as the object's initial velocity, launch angle, the magnitude and direction of the acting forces, and the characteristics of the medium it is traveling through. Analyzing the trajectory allows for prediction of the object's future position, and its design or adjustment to achieve a desired outcome. Trajectories can be complex curves or simple straight lines.

Trajectory meaning with examples

• The rocket's trajectory was precisely calculated to deliver its payload into a specific orbit. Engineers meticulously adjusted its thrust to maintain the planned curve as the rocket ascended, monitoring its position with sensors to make mid-course corrections to stay on track. Failure to calculate the perfect path through the atmosphere, taking into account wind speed, temperature and fuel consumption could result in mission failure. The trajectory was key to reaching its designated destination in space.
• The baseball player hit a soaring home run, its trajectory arcing beautifully over the outfield fence. The ball's path was shaped by the force of the bat, the pull of gravity, and wind resistance. The commentator described how the perfect timing allowed a strong projection to a high point before falling into the stands. The player's skillful swing and the ball's aerodynamic properties influenced the trajectory, showcasing the elegance and power of the hit for the onlooking crowd.
• The meteor's fiery trajectory across the night sky captivated onlookers. Witnesses were astonished at the brightness of the celestial body's journey. Its path, a result of the meteor's initial velocity and the Earth's gravitational pull, created a momentary spectacle. Some speculated on the meteorite’s possible point of impact. Astronomers use telescopes and radar to document the event and track it using their instruments.
• The golfer carefully analyzed the green to determine the best trajectory for the putt. He evaluated the slope, the distance, and the force necessary to guide the ball into the hole. The slightest miscalculation of the force needed to hit the ball could mean a missed shot. The club’s angle and the ball's spin influenced the trajectory, underscoring the precision required in the sport, with practice and fine-tuning being key to success.
