In Tang poetry, there are lines such as "The Yellow River is far up among the white clouds" and "The endless Yangtze River is rolling in". From the perspective of mechanical energy, the first sentence vividly illustrates the water flow of the Yellow River.

From the previous poem, it can be seen that the water of the Yellow River is high above the sky, and it has gravitational potential energy due to its certain height;

The latter poem can be seen that the Yangtze River The water is flowing and has kinetic energy due to movement.

So the answer is: gravitational potential, moving.
