Key Differences
Trajectory refers to the path a projectile or moving body follows through space as determined by external forces like gravity and air resistance. It often involves calculations of physics to predict motion. Whereas, a path is a general term for the route or course taken by any moving entity, not necessarily influenced by physical forces in a scientific sense.
The concept of trajectory is commonly used in physics and engineering to describe the curved path that an object follows under the influence of external forces. On the other hand, path is a broader term that can apply to various contexts, including physical routes traveled by people or objects and abstract sequences of events or decisions.
Trajectory typically involves mathematical models and equations to predict the position and velocity of an object over time. Whereas path can be described and understood without delving into mathematical or physical principles, focusing more on the sequence or direction of movement.
In the context of projectiles, trajectory is specifically concerned with the shape of the path that the object follows, which can be parabolic, hyperbolic, etc., depending on the initial velocity and the forces acting upon it. Path, however, can refer to any line or course of movement, without implying a specific shape or pattern.
While trajectory is a term that implies movement governed by specific physical laws and forces, path can also refer to metaphorical or non-physical journeys, such as the path of one's career or the path through a piece of software.
