During this lessons pupils will:

  • Recap weight calculations from previous lesson.
  • Recap free body diagrams from previous lessons to prepare for using them in this lesson.
  • Recap Newtons three laws of motion highlighting the second law.
  • Consider and discuss the forces acting on a stationary object.
  • Consider and discuss forces acting on an object at constant speed.
  • Define balanced forces.
  • Consider and discuss forces acting on an object that is accelerating.
  • Define unbalanced forces.
  • Learn how to calculate resultant forces
  • Calculate resultant force for two different situations.
  • Complete a fill in the gaps consolidation task.
