The difference between seesaw and seesaw

There is no difference between seesaw and seesaw, both refer to seesaw, and seesaw is the wrong word for seesaw.

The seesaw is a children's game tool. Install a shaft in the middle of a long, narrow and thick board. Then put it on a post, and two people sit at both ends, pedaling the ground in turn, so that one end lifts and the other end falls, and so on. The game is just for fun.

When playing the seesaw, the seesaw rotates, but the situation of people playing the seesaw is more complicated. If the state of man and seesaw remains the same, then man and seesaw rotate together. If people are always vertical to the ground, then people are moving in translation. If people are still shaking at will when playing on the seesaw, then people's movement is not rigid-neither translation nor rotation.

Safety measures of seesaw

1. Only one child can sit at one end of the seesaw. If the weight difference between the two children is too big, you can discuss with them and change to a child with similar weight to play with instead of sitting on the other child at the lighter end.

Two children should sit on the seesaw face to face, not upside down, but back to back.

3. Let the child hold the handle tightly with both hands, and don't try to touch the ground or empty-handed. Put your feet in a special pedaling place. If you don't have a pedal, you can hang down naturally. Don't curl up under the seesaw, or the seesaw will press your child's feet.

If other children are playing on the seesaw, keep your distance while waiting nearby. Never put your feet under the upturned seesaw, don't stand in the middle of the beam of the seesaw, and don't try to climb the seesaw that is tilting up and down.
