What is flux? Flux: Flux is scalar quantity equal to the dot product of the measured vector passing a given area. Usual equation use to measure flux is given as $$\Phi = \vec{V}.\vec{A} = VAcos\theta $$ where, {eq}\Phi {/eq} is the flux ...
今天翻看英文的物理课本,发现一个问题,书里提到speed is a scalar quantity(标量),velocity is a vector quantity(矢量),但speed是速度,velocity是速率,这和高中物理书上所说的速度属于矢量,速率属于标量不是相反吗?望高人指点. 相关知识点: 试题来源:
