Well, actually, I've got everything you need for inventory.
So...
In the study of the air movement, sometimes it's easier not to use the model. It's a pattern. It's a model that sees the environment as a free
In this model, the motion from the particle represents the video trajectory and the current line.
The motion vector from the particle is called a dynamic point space, somewhere a particle is in the process of its movement.
At this point, the particle velocity vector in all the trajectories are directed towards the relevant movie half.
The current line is a line drawn from the points where the moving particle is at a fixed point of time.
And the particle velocity vectors are directed towards relative vibration, as well as the trajectory.
Trajectory and current are different because the trajectory describes the movement of one particle at different moments of time,
And the current is the motion of particle focus in every fixed moment of time.
On a certain condition, the trajectory and the current line make up
It happens if every fixed point of the line, the current velocity vectors don't change over time, the size and direction.
And you can think that at every fixed moment of time, the velocity of the air particles in this current is equal.
