Power Calculations - AQA GCSE Physics Practice Book

Power appears in multiple topics across Physics and students need to switch fluently between P = E/t and P = W/t depending on context. This AQA GCSE Physics workbook builds that flexibility with 12 scaffolded questions using the EVERY method framework.

The EVERY method breaks each calculation into clear steps: Equation, Values, Enter values into the equation, Rearrange if needed, Your units. Every question has a structured EVERY table for students to complete, building a consistent problem-solving habit. Questions get progressively harder: Q1-3 are straightforward, Q4-6 introduce unit conversions, and Q7-12 require rearranging the formula.

What’s inside:

• 12 progressive questions on Power (P = E/t and P = W/t)
• Structured EVERY method table on every question page
• Progressive difficulty: simple substitution, then unit conversions, then rearranging
• Self-assessment tracker with “What made me stuck?” reflection checklist
• Full worked answers for all 12 questions using the EVERY method steps

AQA specification reference: 6.1 Energy (Combined Science and Triple Physics)

Power calculations require students to divide energy transferred or work done by time. Contexts include electrical appliances, human performance, and mechanical systems. Students also convert between watts and kilowatts.

Common student mistakes this workbook addresses: confusing power with energy (power is the rate of energy transfer, not the total), using time in minutes without converting to seconds, mixing up watts and kilowatts, and not rearranging correctly to find energy or time.

Suitable for AQA GCSE Combined Science and Physics (Triple). Works for both foundation and higher tier students.
