Compared with people on the ground, it is an upward movement, and the direction of the China flag remains unchanged during the flagpole movement, so the movement of the national flag is a translation phenomenon. There are both up-and-down translation and horizontal translation.
The movement of the national flag is uniform, and the speed of this uniform movement is determined by the length of the national anthem and the height of the flagpole.
When people walk, they move in translation, and the phenomenon that the displacement changes in two dimensions is translation, while the electric fan is rotation. Translation means that all points on the map move equidistantly along a straight line in the same plane. This kind of graphic movement is called graphic translation movement, which is called translation for short.
