Key examiner messages
Top priorities from the principal examiner before you revise
Many students excelled at standard numeric applications, such as projectile range calculations, basic moments equations, and simple series/parallel resistance calculations.
However, significant marks were lost in descriptive questions requiring rigorous physical reasoning.
Specifically, in Unit 1, the asterisked Quality of Written Communication (QWC) question on terminal velocity (Q14) suffered from a lack of systematic step-by-step force analysis.
In Unit 2, explaining the photoelectric/photon model of light via toy stones (Q15) saw students failing to contrast the photon model explicitly with the continuous nature of wave energy transfer.

Command word playbook
How to match each command word to the expected response style
Give reasons and link mechanism to outcome; each point needs a because/so chain.
Match the expected response style for “Determine” questions.
Match the expected response style for “that” questions.
Apply knowledge to an unfamiliar context; concise, practical points score best.
Match the expected response style for “State” questions.
State features in sequence or list observable properties — do not explain causes unless asked.
Weigh arguments for and against with evidence; end with a supported judgement.

Examiner notes & key calculations
- Newton's Third Law in Fluids: In Unit 1 Q19, candidates struggled to recognize that the upthrust acting upward on the submerged sphere is accompanied by an equal and opposite downward force on the liquid, which is registered as an increased reading on the balance.
- Structural Support Scaling: In Unit 2 Q17, many failed to scale the weight of the bridge road down by a factor of 500 when evaluating the tension supported by a single suspending cable, resulting in an incorrect wave speed v=T/μ v = \sqrt{T/\mu} v=T/μ.
- Graph Rearrangement: In Unit 3 Q4, setting up the LED activation potential equation in the form of y=mx+c y = mx + c y=mx+c to prove a straight-line plot was frequently missed or incorrectly grouped.
