从小开
始练的,或者有舞蹈体操基础的, 才能做得像关mm那样漂漂 :)
我们的冰通常都很平的, 今天特倒霉赶上我百年不遇练sprial, 一头扎进百年不遇的坑
里 :) |

就是说只考虑重力和平面支撑力的作用, 不考虑其他力.
如果没有摩擦力, 这陀螺的下场会怎样?

那么进一步设想: 陀螺如果没速度的话, 肯定就倒了. 如果速度很高就能一直不倒.
那中间一定有一个临界点吧? 在那个速度上, 到底是倒还是不倒?
能不能大致讲讲式子怎么列? 怎么能算出来陀螺不倒?

It is a tree
A deep wound cuts though leaving a scary scar
The memory of a lightening strike, years before
There is only one branch that is alive
You can tell from the fruits
Heavily still
Walking down the hill
It becomes a woman
She bends down to plant seeds
The vines break the ground and sprial in the air
They cover her body with small hands and mouths
Turning her into an old basket
And then I am a child
Floating in the space like a rainbow trout
The sun shines dimmly below

Explanation: How did spiral galaxy ESO 510-13 get bent out of shape? The disks of many
spirals are thin and flat, but not solid. Spiral disks are loose conglomerations of billions of
stars and diffuse gas all gravitationally orbiting a galaxy center. A flat disk is thought to be
created by sticky collisions of large gas clouds early in the gal |
