我若是抛铁锤，那么质量重心，也是唯一的质量重心，会沿完美抛物线运动，就像一颗网球。

If I throw up a hammer, then the center of mass and only the center of mass will just go along a perfect parabola as if it were just a tennis ball.

youdao

在所有的趋势中，抛物线运动通常发生在0% - 38%和62% - 100%菲波纳奇水位。

Parabolic movement tends to occur between the 0%-to-38% and 62%-to-100% Fibonacci levels in all trends.

youdao

Then he knows it's going to go up, it's going to curve, follow some kind of parabola, then his hands go there to receive it.

所以他就知道,这颗糖会先向上,再向下,沿着某条抛物线运动,然后他就能判断在哪里接住糖
