A vector quantity tells us about the magnitude and direction of an object.
It changes with change in the direction or magnitude.
Example, Force is a vector quantity. To know the force on an object we need to know it's numerical value and and in which direction it is applied.
Other examples :-
- Velocity
- Displacement
- Acceleration
--------------
A scalar quantity tells us only about the magnitude and not direction.
It changes with change in the magnitude.
Example, Speed is a scalar quantity. It does not need a direction, we can find speed with magnitude itself.
Other examples :-
- Time
- Distance
- Density
