Folk Sports

In folk culture, playing the crossboard is a form of fitness sport; it is highly entertaining and is popular among ethnic minorities such as the Korean ethnic group and the Russian ethnic group.

2 Principles

The see-saw principle is based on the lever principle, where the pressure of a person on a see-saw is both the force and the resistance. The distance from the person to the fixed point on the see-saw is the force arm.
The gravity acceleration causes a up-and-down motion, where the higher object has a larger gravity acceleration than the lower one, so the higher one falls down, and simultaneously, under the action of the lever principle, the lower one is lifted up, and this cycle continues.
