* Scalar: A scalar quantity is a physical quantity that has only magnitude. It can be represented by a single number and a unit. Examples include:

* Temperature: 25 degrees Celsius

* Mass: 5 kilograms

* Speed: 60 kilometers per hour

* Time: 3 minutes

* Vector: A vector quantity, on the other hand, has both magnitude and direction. It is represented by an arrow whose length represents the magnitude and whose direction points in the direction of the quantity. Examples include:

* Velocity: 60 kilometers per hour east

* Force: 10 Newtons downwards

* Displacement: 5 meters to the north
