AQA GCSE Physics Energy Stores and Transfer Pathways Explanations Worksheet
AQA GCSE energy-stores worksheet with answers. Explain physical changes, distinguish stores from pathways and track dissipation in applied scenarios.
What is covered
Questions and skills covered
The worksheet contains 6 pages of printable questions. A separate 6-page solutions PDF makes it easy to mark, review or share answers after the activity.
- Named objects and energy stores
- Chemical battery store versus electrical pathway
- Hand-cranked hoist GPE and thermal energy account
- Endpoint rest and zero kinetic energy
- Passive lock and unchanged GPE
- Trolley battery/kinetic/retained thermal/heating-out account
- Open system boundary despite internal battery
- Braking and mechanical work against friction
- Electrical transfer to heater then heating water
- Useful versus unwanted depends on intended task
- Cooling water and stipulated closed water-room system
- Common-scale energy blocks and missing budget
- 60% and75% efficiency ratios
- Inconsistent record with150J excess
- Matched water-heating task and400Jinputdifference
- Higher efficiency does not establish shorter heating time
- Counterweight redistribution900=320+580J
About this activity
A repair café tests a hoist, battery-powered trolley and hot-water dispenser. Pupils use an energy account to correct imprecise explanations and judge repair claims.
Before you start
After teaching stores, mechanical/electrical/heating pathways, conservation and efficiency ratios. GPE/KE equations are supplied. No Higher-only improvement statement assumed.
A question from the worksheet
Question3(d),pupilpage3
Is a battery-and-trolley system closed merely because its battery is inside the boundary?
Show the answer
No. In the stated start,80J crosses the boundary by heating to the surroundings; the source being inside does not prevent energy leaving.
Common error: Calling electrical energy a moving object’s store, or saying energy dissipated into the room is destroyed.
