AC9S7U04
Physical sciences
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
Elaborations
- AC9S7U04_E1investigating the effects of applying different forces to familiar objects of the same and different mass
- AC9S7U04_E2analysing the effect of balanced and unbalanced forces on an object’s motion, such as starting, stopping and changing direction
- AC9S7U04_E3measuring 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
- AC9S7U04_E4investigating how Earth's 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
- AC9S7U04_E5investigating how simple machines such as levers and pulleys are used to change the magnitude of force needed to perform a task
- AC9S7U04_E6examining how gravity affects objects in space, including moons, planets, stars, galaxies and black holes
- AC9S7U04_E7analysing the forces acting on boomerangs and how early First Peoples of Australia designed an air foil profile which allowed for multiple variations and applications
- AC9S7U04_E8investigating 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
