英语翻译
Under which of the following conditions is the magnitude of the average velocity of a particle moving in one dimension smaller than the average speed over some time interval?A.A particle moves in the +x direction without reversing.B.A particle moves in the -x direction without reversing.C.A particle moves in the + x direction and then reverses the direction of its motion.D.There are no conditions for which this is true.

英语翻译Under which of the following conditions is the magnitude of the average velocity of a particle moving in one dimension smaller than the average speed over some time interval?A.A particle moves in the +x direction without reversing.B.A par
在下列情况中,求问:相同时间内物体的平均速度小于平均速率的选项是()
A.物体沿+x移动,不掉头
B.物体沿-x移动,不掉头
C.物体沿+x移动,然后掉头
D.上述都不对
选C.因为平均速度=位移/时间,平均速率=路程/时间.既然时间相同,那么不掉头的运动其|位移|=路程,而掉头运动,|位移|<路程,所以|平均速度|<平均速率.

据此,以下条件是粒子移动在一个维度上比一般的速度更小的过一段时间间隔的平均流速的大小?在+ x方向AA粒子的运动而不在-x方向reversing.BA粒子移动无倒车。 CA粒子移动在+ x方向,然后反转其motion.D.There的方向没有任何条件的量,这是真实的。

在下列状况进入一个尺寸小于超过一定的时间间隔平均速度的粒子的平均速度的大小?一个粒子移动在X方向不换向。无换向在X方向移动一个粒子。一个粒子移动在X方向并将其motion.d.there方向是无条件的,这是真的。
