Wikipedia

  1. Trajectory

    A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously. The mass might be a projectile or a satellite. For example, it can be an orbit — the path of a planet, asteroid, or comet as it travels around a central mass. In control theory, a trajectory is a time-ordered set of states of a dynamical system (see e.g. Poincaré map). In discrete mathematics, a trajectory is a sequence ( f k ( x ) ) k ∈ N {\displaystyle (f^{k}(x))_{k\in \mathbb {N} }} of values calculated by the iterated application of a mapping f {\displaystyle f} to an element x {\displaystyle x} of its source.

  1. trajectory

    A trajectory is the path that an object follows through space as a function of time. It can refer to the motion of any object, such as a thrown baseball, a planet orbiting the sun, or a vehicle on its course. It represents a sequence of positions that the object takes over time defined by its speed and direction.

Webster Dictionary

  1. Trajectorynoun

    the curve which a body describes in space, as a planet or comet in its orbit, or stone thrown upward obliquely in the air

  1. Trajectory

    A trajectory is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite, for example. It thus includes the meaning of orbit—the path of a planet, an asteroid or a comet as it travels around a central mass. A trajectory can be described mathematically either by the geometry of the path, or as the position of the object over time. In control theory a trajectory is a time-ordered set of states of a dynamical system. In discrete mathematics, a trajectory is a sequence of values calculated by the iterated application of a mapping to an element of its source.

Examples of trajectory in a Sentence

  1. Daniel Ives:

    They're not going to stay at 80-90 % share of the EV market, but they can keep growing even with much lower market share, we're looking at north of 3 million to 4 million vehicles annually as we go into 2025-26, with 40 % of that growth coming from China. We believe now they are on the trajectory that even without [ the EV ] credits they'll still be profitable.

  2. Mario Draghi:

  5. Brian Lapointe:

    It’s hard to project because we don’t know everything we need to know about the drivers (behind this), we know it’s variable from year to year and that the trajectory is generally going upwards. So based on what we’ve seen in the past, we’re thinking we could continue to see this worsen for years to come. What will it be like in 10 years? Will it be double the size it is now?
