Representation of Scalar and Vector

 Representation of Scalar:

• A scalar is represented by a single value or number without any direction.
• For example, the scalar quantity "temperature" can be represented as 25°C.
  

Representation of Vector:

• A vector is represented by a magnitude and direction.
• It can be represented graphically using an arrow, with the length of the arrow representing the magnitude of the vector and the direction of the arrow representing the direction of the vector.
• Vectors can also be represented algebraically using coordinate notation, where each component of the vector is written as a numerical value with a corresponding unit of measurement.
• For example, a vector representing velocity could be written as (5 m/s, 3 m/s).
