  • 7. INTRODUCTION (Set Induction)
  • 8. SI UNITS OBJECTIVE: To describe the International System of units The International System of Units is the modern form of the metric system. It comprises a coherent system of units of measurement built around seven base units K –Kelvin S – Second m – Meter Kg – Kilogram cd – Candela mol – Mole A - Ampere next >
  • 9. SI UNITS OBJECTIVE: To describe the International System of units < Back > KELVIN (K)
  • 10. SI UNITS OBJECTIVE: To describe the International System of units < Back > SECOND (s)
  • 11. SI UNITS OBJECTIVE: To describe the International System of units < Back > METER (m)
  • 12. SI UNITS OBJECTIVE: To describe the International System of units < Back > KILOGRAM (kg)
  • 13. SI UNITS OBJECTIVE: To describe the International System of units < Back > AMPERE (A)
  • 14. SI UNITS OBJECTIVE: To describe the Base Quantities BASE QUANTITY , BASE UNITS & SYMBOLS Quantity Unit name Unit symbol length metre m mass kilogram kg time second s electric current ampere A thermodynamic temperature kelvin K amount of substance mole mol luminous intensity candela cd
  • 15. SI UNITS OBJECTIVE: To describe the Derived Quantities DERIVED QUANTITY , DERIVED UNITS & SYMBOLS Derived units are formed from multiplication and division of the seven base units and other derived units and are unlimited in number Named units derived from SI base units Quantity Symbol Relationship Dimension symbol Area Volume A V Width x lenght Width x length x height m2 m3 Velocity u,v Displacement/time m/s or ms-1 Accelerate Force a F Velocity/time Mass x acceleration m/s2 or ms-2 Kgms-2 or N Pressure p Force / Area Pascal Work Power W P Force x distance Work/time Joule or Nm J/s or Watt
