  • 平均加速度到底多少呢?

    So what, now, is the average acceleration?

    youdao

  • 意味着一个巨大的加速度

    That means there must be a huge acceleration.

    youdao

  • 位置,这是速度,然后加速度

    This is the position, this is its velocity and this is its acceleration.

    youdao

  • 意味着加速度平行

    So, that means the acceleration is parallel to the position.
