Equilibrium of force

· Centre of gravity and stability
· Couple

By the end of this lesson, students should be able to:
  • define the centre of gravity;
  • define the centre of mass;
  • explain the centre of gravity of different bodies;
  • explain equilibrium in terms of stability of object;
  • state when an object is stable;
  • state the types of equilibrium based on the stability of objects;
  • state the examples of the types of equilibrium based on stability;
  • define couple;
  • define the moment of a couple.
