也不是沿一条抛物线轨迹,因为小球是竖直射出的。
It wasn't going into a parabola because I was shooting it straight up.
物料按抛物线轨迹连续向前作跳跃运动,因此给料槽磨损较小。
The material according to the continuous forward parabolic trajectory for jumping movement, therefore the feeding trough less wear and tear.
空气弹射巧妙地将空气压力和水流反冲技术结合起来,把参与者按照预先计算好的抛物线轨迹抛到空中。
AirKick works propelling participants through the air in a pre-calculated parabolic trajectory using a special combination of air pressure and water recoil technology.
That's correct. So her answer was, if it was a full parabola, then we know it would've been at the ground before I set my clock to 0.
