Yes -i need more data to really see if the final velocity is constant. However, let me look at the distributions of vertical accelerations before the tap.

我确实还得收集更多的数据，看看点击后的速度是不是恒定的，但让我先看看点击之前竖直方向的加速度吧。

The falling object, after traveling a certain distance through the air reaches a final speed, or "terminal velocity," because the object's friction with the air slows the fall.

物体在下落一定距离后由于空气阻力都会达到一个终极速度。

It's very interesting because velocity seems to require two different times to define it -- the initial time and the final time.

这非常有趣,因为速度似乎需要两个时间才能算出来,初时刻和末时刻

Second formula tries to relate the final velocity of some time, t, to the initial velocity and the distance traveled with no reference to time.

第二个式子能把某段时间t的末速度,和初速度,经过的路程联系在一起,并且不引入时间

What is y-y0? The final y is 0, the initial y is 15. You solve for that equation and you will find the final velocity.

-y0是什么,末态的y是0,初态的y是15 你们已经得到,然后你可以找到最终速度
