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.
Greek Lyceum Grade 2 / Physics / Curriculum
Προσανατολισμός Θετικών Σπουδών: structured theory, worked examples, answered practice, and a mastery checklist for Greek Lyceum Grade 2.
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 7 Ω resistor is connected across 21 V. Find current and power.
Physics
Work with diagrams, forces, equations, units, and physical interpretation, not simple formula substitution.
The structure follows the official textbook layout and is used to organise study.
I = 3 A, P = 63 W
Before calculating, explain the key idea from “Οριζόντια βολή” and which conditions must be checked.
The answer should show not only which rule is used for “Οριζόντια βολή”, but also why it is valid here.

Try independently, use the hint if needed, then open the answer guide.
1. Explain the idea and give one correct foundation example for “Οριζόντια βολή”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Οριζόντια βολή” to a physical law or model, correct units, and an interpretation.
2. Solve an application and show every intermediate step for “Κυκλική κίνηση”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Κυκλική κίνηση” to a physical law or model, correct units, and an interpretation.
3. Compare a correct and an incorrect approach and justify the difference for “Κεντρομόλος επιτάχυνση”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Κεντρομόλος επιτάχυνση” to a physical law or model, correct units, and an interpretation.
4. Create a short exam-style question and check your answer for “Ορμή”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Ορμή” to a physical law or model, correct units, and an interpretation.
The areas that usually create mistakes or need extra revision.
Where to start: textbook, daily material, PDFs, videos, and worked examples.
Targeted practice before full tests so coverage is clear.
How to measure progress in this chapter and when it enters a cumulative mock.
What to do after finishing the chapter and how it connects to the next unit.
Note: for the official examinable syllabus of each school year, always confirm with the school, tutor, and current Ministry/IEP announcements.
