The physical principle of kindergarten slide

 

Kindergarten slide board generally fall into two kinds, one is flat, and there's a curved, it is the sliding surface of cycloid. Assuming that both the height of the slide is the same, there are two identical weight children respectively from slide down at the same time, cycloid slide of the kindergarten will be the first person on the ground. Because children in kindergarten can slide on the slide, because by gravity.

 

When the slope of skate board face does not at the same time, if the gravity force component, the greater the slide acceleration will increase, the relatively fast speed increase. Along a straight slide down, slide in the acceleration remains the same, the speed increase steadily. Along the cycloid slide down, start a skateboard slope is very big, make children falling in a very short period of time to get enough of the slip velocity. Although, in the final stages of fall, slope will increase gradually become smaller, the speed slow, but at the moment, have accelerated the decline speed of many.
