Key M1.1 — Changes in motion result from unbalanced forces. M1.2 — Scalar, vector and graphical methods can be used, as appropriate, to describe motion. M1.3 — The collection of data used to describe motion can be accomplished using a range of technologies. M1.4 — Primary and secondary data can be analysed, manipulated and presented in a variety of formats to provide alternative descriptions of motion. Key ideas M2.1 — The relationship between force, mass and acceleration can be analysed qualitatively and quantitatively using algorithms and graphical techniques. M2.2 — The directional relationship between acceleration and net force can be analysed using vector diagrams. M2.3 — The laws of conservation of energy and momentum can be used to analyse and describe motion of objects in simple and complex situations. M2.4 — An understanding of the nature of fields (gravitational, magnetic and electric) and their interactions with matter can be used to analyse and predict the motion of an object. M2.5 — Relative rates of change are useful measures when analysing the motion of an object. Key ideas M3.1 — The propagation of light demonstrates the concepts of wave–particle duality, quantisation of energy and probability waves. M3.2 — Classical and relativistic theories are used to describe motion in different circumstances.
