 What are the differences between scalars and vectors?

 

Scalars  vectors
Physical quantities having magnitude only but no direction are called scalar quantities. Physical quantities having magnitude and direction are called vector  quantities.

  Scalar quantities are completely described by:

1:a number

2:a suitable unit

vector quantities are completely described by:

1:a numbers

2:by a suitable unit

3:By certain direction

Scalar quantities are added ,subtracted ,multiplied and divided by simple arithmetic rules.      Vector quantities cannot be added ,subtracted,multiplied and divide by simple arithmetical rules.

Examples of scalar quantities

  • Speed
  • work
  • distance
  • energy
  • power
  • Temperature
  • Volume
