D.1-Supplied constants and data

Use supplied constants such as g, c, e, u, particle masses, Avogadro constant, gas constant, Boltzmann constant, gravitational constant, permittivity of free space, Planck constant and Stefan-Boltzmann constant.

Use d.1-supplied constants and data to connect the rule to the data and decision in the question.

This matters because d.1-supplied constants and data determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply d.1-supplied constants and data to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: D.1-Supplied constants and data is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.

D.2-AS formulae supplied in Papers 1, 2 and 4

Select and apply supplied AS formulae for uniformly accelerated motion, hydrostatic pressure, upthrust, sound-wave Doppler effect, electric current and resistor combinations where relevant.

Use d.2-as formulae supplied in papers 1, 2 and 4 to connect the rule to the data and decision in the question.

This matters because d.2-as formulae supplied in papers 1, 2 and 4 determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply d.2-as formulae supplied in papers 1, 2 and 4 to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.

D.3-A Level formulae supplied in Paper 4

Select and apply supplied A Level formulae for gravitational potential, ideal gases, simple harmonic motion, electric potential, capacitors, Hall voltage, alternating current, radioactive decay, acoustic impedance, Stefan-Boltzmann law and Doppler redshift.

Use d.3-a level formulae supplied in paper 4 to connect the rule to the data and decision in the question.

This matters because d.3-a level formulae supplied in paper 4 determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply d.3-a level formulae supplied in paper 4 to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.

D.4-Choosing formulae without losing physical reasoning

Decide whether a supplied formula is appropriate, identify each variable, convert units, rearrange correctly and explain the physical meaning of the result rather than relying on substitution alone.

Use d.4-choosing formulae without losing physical reasoning to connect the rule to the data and decision in the question.

This matters because d.4-choosing formulae without losing physical reasoning determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply d.4-choosing formulae without losing physical reasoning to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
