Curriculum content descriptions
investigate and represent balanced and unbalanced forces, including gravitational force, acting on objects, and relate changes in an object’s motion to its mass and the magnitude and direction of forces acting on it (AC9S7U04)
Elaborations
- investigating the effects of applying different forces to familiar objects of the same and different mass
- analysing the effect of balanced and unbalanced forces on an object’s motion, such as starting, stopping and changing direction
- measuring the magnitude of a force using a force meter and representing the magnitude and direction of forces acting on an object using force arrow diagrams
- investigating how Earths gravitational force is the attractive force which pulls objects to the centre of Earth and its magnitude is related to the mass of an object
- investigating how simple machines such as levers and pulleys are used to change the magnitude of force needed to perform a task
- examining how gravity affects objects in space, including moons, planets, stars, galaxies and black holes
- analysing the forces acting on boomerangs and how early First Peoples of Australia designed an air foil profile which allowed for multiple variations and applications
- investigating the effect of forces through the application of simple machines, such as the bow and arrows used by Torres Strait Islander Peoples or the spearthrowers used by First Peoples of Australia
