独木船的加速度方向如何?
因此我决定,在此处改变正方向,加速度方向就始终为正了,符号变了。
So the moment that I decide to define this the plus direction will also come out to be the same sign as this one so I flip the signs there.
研究表明,追逃双方机器人的控制作用使得彼此的加速度方向一致时,双方都取得最优控制策略,同时也证明了微分对策方法在处理碰撞问题时的有效性。
The research indicates that the controlling strategy is optimal when they have the same acceleration direction, and the differential games are efficient in dealing with collision problem.
You will learn in 8.02 that if you have a charged body changing direction, that constitutes an acceleration.
你们将在8。02中学到,如果一个带电体改变方向时,产生一个加速度。
You cannot have a spring pulled only at one side, because then it will then accelerate with infinite acceleration in that direction.
你不可能对弹簧只施加一边的拉力,因为那样的话弹簧就会以无穷大的加速度加速,就在这个方向上
And, you know acceleration means either change of speed or change of direction.
你知道加速度意味着,不是改变速度就是改变方向。
