Velocity is an example of a vector quantity. This can be described by two things, the speed, which is the rate of change of distance travelled with respect to time, and also the direction in which it is travelling. Similarly, force can be described by the size of magnitude of the force...
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 ...

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...
1 Which is a vector quantity?(1) electric charge(2) electric field strength(3) electric potential difference(4) electric resistance5 A machine launches a tennis ball at an angle of25° above the horizontal at a speed of 14 metersper second.The ball returns to level ground.Which combination...
To understand the difference between multiplying a vector by a real number and multiplying a vector by a scalar, we can break it down into clear steps: 1. Definition of Vectors and Scalars: - A vector is a quantity that has both magnitude and direction (e.g., force, velocity). - A ...
Give an example of a physical quantity having neither unit nor magnitude. What type of quantities are the ones which can be completely described by magnitude only? Explain how to calculate displacement. What is meant by irrotational vector field? Starting with the Gaussian form of ...
Drag a value into theMeasurebox and make sure that the visual is shaped as a circle. If the visual isn't displaying anything, from theFieldspane, drag theQuantityfield into the developer visual. Resize the visual. Notice that the circle and text scale to fit the dimensions of the visual....
If the visual isn't displaying anything, from the Fields pane, drag the Quantity field into the developer visual. Resize the visual. Notice that the circle and text scale to fit the dimensions of the visual. The update method is called when you resize the visual, and as a resu...
For example suppose someone sees the following L=18m This could mean that L (whatever it is) equals the product of 18 and the quantity“m” (whatever “m” may be). Therefore, it is essential to leave a space between the magnitude and the dimension. If we want to show the dimension ...
