Scalar and vector analysis

Let us discuss today about two quantities called scalars and vectors. Suppose you are going in your car or bike. Your vehicle must have speedometer which shows the speed. Let the speed is 60 km/hour. Now suppose you have certain instrument which shows that you are going in north direction with 60 km/hour.

So the 60 km/hr means only the magnitude or value. So the quantities which have only magnitudes or values are called scalars.

But the 60 km/hr in north direction means the quantity has value as well as direction in it. These quantities are called vector quantities.

Therefore the more technical definitions will be: Continue reading “Scalar and vector analysis”
