What is scalar and vector quantity?
The quantities having magnitude and unit is called scalar quantity.Some of these quantities have direction also but vector laws are not applied.
Some examples of vector quantities are:
- Electric charge
The quantities which have magnitude,unit and direction are called vector quantities.These quantities also follow triangle law of addition.Some examples of these quantities are:
