Examiner Insights

Based on analysis of 5 official Cambridge documents (2023, 2025)

Unit conversion errors — minutes to hours, kW to W, cm to m, km³ to m³

“Incorrect answers chosen involved using an incorrect equation, not converting minutes to hours or not converting watts to kilowatts.”— Paper 1, May/June 2023

How to fix: Write every conversion: 1 hour = 60 min (not 100). 1 kW = 1000 W. 1 km = 1000 m, so 1 km³ = (1000)³ m³ = 10⁹ m³. For time: 3h 20min = 10/3 hours (not 3.20). Always convert BEFORE substituting into equations.

Equation rearrangement errors — dividing instead of multiplying

“The most common incorrect answer was option A, indicating that candidates had not rearranged the equation correctly and instead they divided force by distance.”— Paper 1, May/June 2023

How to fix: Write the formula first. Then rearrange algebraically BEFORE substituting numbers. Check: if speed = distance/time, then distance = speed × time (multiply, not divide). Use the formula triangle if needed, but always verify the rearrangement makes sense.

'Show that' questions — manipulating numbers without stating the formula

“When asked to 'show that' a quantity has a particular value, candidates must demonstrate that they know the formula they are applying. Manipulation of numbers given in the question to achieve the correct numerical answer is insufficient.”— Paper 4, May/June 2023

How to fix: For 'show that': (1) Write the formula in words or symbols. (2) Substitute ALL values with units. (3) Calculate to more decimal places than the given answer. (4) State the conclusion. Just rearranging the given numbers without showing the physics earns zero.
