Do I understand streamline, streakline and pathlines correctly?

    Pathline:
    When you can see a particle with your eyes and the trajectory of the particle.

    Streakline:
    When the particle is "invisible" (such as air) and you have to add paint or dye or something similar in order to see its trajectory.

    Timeline:
    When a particle has a pathline, except the trajectory of this pathline depends on the time.

    Streamline:
    Any path that is tangential on the velocity field.
