Difference between scalar and vector quantities
| SCALAR QUANTITIES | VECTOR QUANTITIES |
|
Definition |
|
| The physical quantities. which are completely specified by their
magnitude only, are called scalar quantities. |
The physical quantities, which are completely specified by their magnitude direction both are
called vector quantities |
|
Characteristics |
|
| Scalar can be added, subtracted and Multiplied by a simple arithmetic method. | They are added, subtracted and multiplied by the geometric or trigonometric methods.
|
|
Representation |
|
| Scalar can be represented by a number i.e.
50 seconds. |
A vector can be represented graphically by a directional line segment with an arrow. |
|
Examples |
|
| Mass, volume, time, distance, speed, density, work, energy, temperature, etc. | Area, displacement, velocity, acceleration
force, momentum, torque, etc. |
