15.0.0: SCALAR AND VECTOR QQUANTITIE:
15.0.0: SCALAR  QUANTITIES:
Scalar quantities are those quantities that have only magnitudes. They do not have directions.

EXAMPLES OF SCALAR QUANTQUANTITIES:

• (I) speed 
• (ii) distance
• ( iii) time 
• ( iv) volume 
• (v) area 
• (vi) temperature
• (vii) spfield

VECTOR QUANTITIES:
Vector quantities are those quantities that have both magnitudes and directions.

EXAMPLES OF VECTOR QUANTITIES:

• Displacement
• Weigh
• Force
• Acceleration due to gravity
• Electric field
• Magnetic field

DIFFERENCES BETWEEN SCALAR AND VECTOR QUANTITIES:
      Scalar quantities.                                               Vector quantities

• It has only magnitude.                                   It has magnitude and direction
• it direction can not be determined.            It direction can be determined
• It is not represented by line and arrow.    it is represented by line and arrow
• 
  

SIMILARITIES BETWEEN SCALAR AND VECTOR QUANTITIES:

• They are physical quantities in physics
• They both have magnitudes
• Their magnitudes can be determined by calculations

REPRESENTATION OF VECTOR QUANTITIES:

Vector quantities are represented with a line and an arrow head. The line represent the magnitude/ value/ size of the vector quantity while the arrow head represent the direction of travel of the vector quantity. This is as shown below:
