英语中的speed和velocity,哪个是速度哪个是速率?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....
Why is it called vector quantity? Vector, in physics,a quantity that has both magnitude and direction. ... To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination. One of these is vector addition, written symbolically as A + B = C (...
Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity. Thus, a velocity of 50 km/h due east, on acceleration of 9.8 m/s 2 vertically downward, and a force of 15 N at an angle of 30掳 are all examples of vector quantities.J O...
向量(vector) 是既有长度又有方向的量 (a quantity that possesses both magnitude and direction) 如图: 位移向量 位移向量的大小代表前进的距离大小,而向量的方向代表位移方向。 和向量相对的是标量。标量 (scalar, scalar quantity) 是有大小没有方向的量(用实数表示) 向量定义 给定一个列向量 a: a=\begin...
A scalar quantity is the magnitude of a measurement, while a vector quantity is the magnitude plus a direction. A vector quantity is a scalar plus a direction. What does scalar mean? Scalar means a magnitude: how small or large something is. A scalar quantity has one dimension only and no...
形容词用法:Temperature is a scalar quantity that describes the hotness or coldness of an object. 翻译:温度是一个标量,用于描述物体的冷热程度。 名词用法:In linear algebra, a scalar is a single number that can be multiplied by a vector or a matrix. 翻译:在线性...
