# Difference between scalar and vector quantities

Any quantity which can be measured by any method is called a physical quantity. all the  physical quantities are divided into two groups.

1. scalar quantities
2. vector quantities

### Scalar Quantities

Definition : The physical quantities, which are completely specified by their magnitude only are called scalar quantities.

Examples : Mass, time, distance, speed, work, energy, temperature charge etc

### Vector quantities

Definition : the physical quantities which are completely specified by their magnitude and direction both ae known as vector quantities.

Examples : Displacement, velocity, acceleration, force, momentum, torque, etc.

### Difference between scalar and vector quantities

 SCALAR QUANTITIES VECTOR QUANTITIES Definition The physical quantities. which are completely specified by theirmagnitude 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, accelerationforce, momentum, torque, etc.
