What is the difference between a scalar quantity and a vector quantity in physics, and provide examples of each.相关知识点: 试题来源: 解析 标量只有大小,矢量有大小和方向;例子:标量如质量、温度,矢量如速度、力 1. **标量定义**:标量仅由数值大小描述,无方向。例如质量(kg)和温度(℃),只需数值...
一矢量（vector）（scalarquantity）：只具有大小而没有方..
Direction enables us to find out where the glass is. One quantity that is a vector quantity is the velocity of a moving object. Though you can get away when you say that the speed of the moving car is 50mph, the same cannot be said when you are talking in terms of its velocity. V...
scalar是一个英语单词,主要用作形容词和名词,具体释义如下: 作为形容词 scalar意为“标量的;数量的;梯状的,分等级的”。例如: scalar multiplication:纯量乘法;标量乘法。 scalar field:标量场;纯量场;数量场。 scalar potential:标量势;标量位。 scalar quantity:数量,纯量,标量。 scalar wave:标量波。 作为名...

A vector quantity has both a magnitude and a direction, and therefore is represented by a numeral and a directional indication.In this lesson, we will discuss what a scalar quantity is and how it is used in physics. You will learn how to identify a scalar quantity, as well as how to ...
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...
(b) The velocity of a car is a vector quantity because it describes both the speed of the car (magnitude) and its direction of movement. (c) The temperature of a room is a scalar quantity because it provides only a numerical value to represent the thermal condition, without any direction...
