Years 7 to 10 Physics

Levels 7 & 8

Change to an object’s motion is caused by unbalanced forces acting on the object ; Earth’s gravity pulls objects towards the centre of Earth.

Energy appears in different forms including movement (kinetic energy), heat, light, chemical energy and potential energy; devices can change energy from one form to another.

Light can form images using the reflective feature of curved mirrors and the refractive feature of lenses, and can disperse to produce a spectrum which is part of a larger spectrum of radiation.

The properties of sound can be explained by a wave model.

Levels 9 & 10

Electric circuits can be designed for diverse purposes using different components; the operation of circuits can be explained by the concepts of voltage and current.

The interaction of magnets can be explained by a field model; magnets are used in the generation of electricity and the operation of motors.

Energy flow in Earth’s atmosphere can be explained by the processes of heat transfer.

The explanation of the motion of objects involves the interaction of forces and the exchange of energy and can be described and predicted using the laws of physics.
