- the use of models, as in the particle model of matter or the wave models of light and of
sound
- the concept of cause and effect in explaining such links as those between force and
acceleration, or between changes in atomic nuclei and radioactive emissions
- the phenomena of ‘action at a distance’ and the related concept of the field as the key to
analysing electrical, magnetic and gravitational effects
- that differences, for example between pressures or temperatures or electrical potentials,
are the drivers of change
- that proportionality, for example between weight and mass of an object or between force
and extension in a spring, is an important aspect of many models in science
- that physical laws and models are expressed in mathematical form.
All of these key ideas will be assessed as part of this qualification, through the subject
content.
