Charge, current, and potential difference
Charge is a property, current is charge flow rate, and potential difference is energy per unit charge. Keep these definitions distinct.
A Level Year 13 / Physics / Curriculum
Fields and circular motion: structured theory, worked examples, answered practice, and a mastery checklist for A Level Year 13.
Unit
The essential chapter ideas in a clear sequence before practice.
Charge is a property, current is charge flow rate, and potential difference is energy per unit charge. Keep these definitions distinct.
Draw a closed circuit with correct symbols. Apply charge conservation at junctions and energy conservation around loops where required.
Field lines indicate direction and relative strength. In induction, changing magnetic flux is linked to induced potential difference.
Physics
Follow the method step by step and check why every step is valid.
A 5 Ω resistor is connected across 10 V. Find current and power.
Physics
Link each topic to equations, units, data handling, and required practical thinking.
The structure follows the official textbook layout and is used to organise study.
The areas that usually create mistakes or need extra revision.
I = 2 A, P = 20 W
Before calculating, explain the key idea from “Motion in a circle” and which conditions must be checked.
The answer should show not only which rule is used for “Motion in a circle”, but also why it is valid here.
Fields and circular motion
Try independently, use the hint if needed, then open the answer guide.
1. Explain the idea and give one correct foundation example for “Motion in a circle”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Motion in a circle” to a physical law or model, correct units, and an interpretation.
2. Solve an application and show every intermediate step for “Gravitational fields”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Gravitational fields” to a physical law or model, correct units, and an interpretation.
3. Compare a correct and an incorrect approach and justify the difference for “Electric fields”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Electric fields” to a physical law or model, correct units, and an interpretation.
4. Create a short exam-style question and check your answer for “Capacitance”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Capacitance” to a physical law or model, correct units, and an interpretation.
Where to start: textbook, daily material, PDFs, videos, and worked examples.
Targeted practice before full tests so coverage is clear.
