Outcomes

Pupils should be able to give examples for, label and name a range of forces including

  • Applied Force (push/pull)
  • Frictional Forces
  • Normal Force (Reaction)
  • Gravitational Force (Weight/gravitational pull)

Specification References

1.7 Express a force as a push or a pull of one body on another

1.8 Identify various types of force (e.g. gravitational, electrostatic etc)

Starter

Discuss how we represent forces. Lead the discussion to the idea of a free-body diagram. Pupils need to know that the direction of the arros is important as is the size. Also they should know that the diagram shows the forces acting on one object.

Main Body of Lesson

  • The force circus has now been split in three. To get through the circus I suggest talking through each station with the entire group having different pupils undertaking the experiment as you go. There is also a powerpoint with some simple definitions of the 4 forces covered in this lesson.
  • Copies of the work sheets can be found in the shared folder

Plenary

Mini whiteboards and some free-body diagrams on the board.

Homework

There is a homework sheet with some freebody diagrams and questions in the shared folder. The sheet includes some questions on thrust and air resistance (which will be covered next lesson)

Additional Information

Resources Required

  • Frictional- slope with different objects (car, glass block and wooden block) where they change and measure the angle + hovercraft
  • Gravitational – different masses on a Newton Scale, planetry model
  • Applied Force – Push or Pull and Thrust – pulling brick with Newton meter, sand to pour onto a balance
  • Normal Force- block and strong card
