Displacement, Initial velocity, Finalvelocity, Acceleration and Time.
位移，初速度，末速度，加速度和时间。

Finallyafter steering and obstacle avoidance the finalvelocity is calculated.
最后在转向和避障之后，最终速度就计算出来了。

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