  • Physics
    The study of laws of natural phenomenon
  • Measurements are inevitable in physics
  • Measurements
    Quantities which need units
  • Types of quantities
    • Basic quantities
    • Derived quantities
  • Basic quantities
    • Quantities which cannot be further simplified
    • There are 5(+2) basic quantities
  • Derived quantities
    • Quantities obtained by operations on basic quantities
  • There are 5 basic quantities
  • Basic quantities
    • Mass (m)
    • Length (l)
    • Time (t)
    • Electric Current (I)
    • Temperature (T)
    • Amount (n)
    • Light intensity (c)
  • SI unit
    Unit of measurement
  • SI units
    • kilogram (kg)
    • metre (m)
    • seconds (s)
    • Ampere (A)
    • Kelvin (K) or Celsius (°C)
    • mole (mol)

  • Mass
    Amount of matter
  • Length
    Distance between two points
  • Other than the 5 basic quantities, all other quantities are derived quantities
  • Derived quantities have a formula
  • Deriving SI units for:
    1. Density
    2. Weight
  • Density
    mass / volume (kg/m³)
  • Weight
    mass x gravitational acceleration (kg m/s²)
  • Deriving SI units for:
    Speed (constant + speed)
  • Speed
    distance / time (m/s)
