Question

WHAT IS DIFFERENCE BETWEEN VECTOR AND SCALOR QUANTITY

Answer 1

scalar quantity have only magnitude whereas vector quantity have both magnitude and direction

Answer 2

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
