Although the ancients did not invent the word centrifugal force, our ancestors saw the influence of river shape on alluvial plain from the effect of flood on riverbed and embankment: the river surrounds the plain, and when flood occurs, the river will scour the embankment opposite the plain, and the riverbed will extend outward to increase the area of the plain; When the river turns back to the plain, the flood will wash away the soil in the plain and reduce the area of the plain. In other words, our ancestors have long recognized that when an object moves in a circle or arc, it will produce an outward force, which is basically consistent with Newton's centrifugal force theory.
