 A scalar quantity is a quantity that has
magnitude only.
 Examples include:
Mass
Temperature
Energy
Speed
Distance
Pressure
 Scalar quantities are added additively e.g.
5kg + 10kg = 15kg
25J + 30J = 55J
8m/s + 10m/s = 18m/s
 A vector quantity has both magnitude and
direction.
 Examples include:
Force
Velocity
Weight
Electric current

 One way to represent a vector is by an arrow and the length of the vector
drawn to scale, as the magnitude
