一矢量（vector）（scalarquantity）：只具有大小而没有方..
Scalar quantity has magnitude only,example arespeed/time/distance/massVector quantity have both magnitude and direction,example areweight/force/displacement(Any one example for each case)Show the direction is the opposite from the originalPeriod is the time taken for one complete oscillation of the ...
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...
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 ...
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...
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...

If it took a car 2 hours to reach its destination while traveling 30 km per hour to the east, then the time of 2 hours is a scalar quantity while the velocity of 30km/h to the east is a vector quantity. Note that the velocity had a scalar quantity of 30km/h which is also ...
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...
