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 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...
3.A scalar quantity: a) always has mass b) is a quantity that is completely specified by its magnitude c) shows direction d) does not have units 4. A vector quantity a) can be a dimensionless quantity b) specifies only magnitude
A vector has magnitude and direction. Since trying to satisfy myself of the difference between these two objects, I have learned that scalars can be real numbers and are related to the operation of scaling a vector. -7 is a scalar quantity althought it appears, to me at least, to be...

Why is displacement a vector quantity? What is the difference between speed and acceleration? How can someone travel a distance of 41 meters but have a displacement of 0 meters? What is the main difference between speed and velocity?
While speed is a scalar quantity, velocity is a vector. A simple way to describe the difference between them is that velocity brings information about the direction of the movement. For example, a car is traveling on a straight-line highway that connects south and north of a territory. If...
Speed is a scalar quantity, which means it only has magnitude and doesn't have a direction. It tells us how fast an object is moving without regard to its direction. On the other hand, Velocity is a vector quantity, meaning it has both magnitude and direction. This distinction makes ...
