If an arm is stretched forward under water resistance is increased and a reaction force back ward is developed both of which would contribute to negative acceleration.
如果手臂在水中是向前伸展则阻力会随之增加而向后方的反作用力也会出现，二者都会产生负加速度。
Here, when it makes this rounding curve the velocity is positive here, but on this side it's negative so what does that mean for the acceleration?
这里，就在曲线的拐角，速度一开始是正的，不过在另一边就成了负的，就加速度而言这又意味着什么呢？
However, if you take the average acceleration t1 0 that is smaller than zero 0 because here the velocity is zero but here the velocity is negative.
可是如果考虑到,和t5之间的平均加速度5，between，t1，and，t5,那么它将小于,因为这里速度为,但是到了这里却是负值。
The acceleration is positive if the speed is increased, negative if speed is decreased.
速度增加的加速度为正加速度，速度减少的加速度为负加速度。

Acceleration: a change in velocity with respect to time. Values are either positive or negative with standard orientation.
加速度：速度相对时间的变化。加速度值根据确定的方向而为正或者负。
