The principle of the seesaw is the principle of leverage. The pressure of a person on the seesaw is the power and resistance, and the distance between the person and the fixed point of the seesaw is the power arm and the resistance arm respectively.
The downward acceleration leads to one up and down, the high one’s downward acceleration is greater than the low one, so the high one drops, and at the same time the lower one is lifted up under the action of the principle of leverage, and so on.
We all know that playing
seesaw is a kind of amusement equipment for children that requires cooperation to play. It requires good cooperation between two children when playing. Therefore, this kind of children’s amusement equipment is not suitable for children under 5 without the company of an adult. Children play, because children still don’t know how it feels to take care of each other, so they don’t want to play and just come down, and don’t care about the other side’s situation at all, and accidents are often easy to happen.
