Define the system
Choose the body or system, define a positive direction, and mark every force or motion quantity before writing an equation.
Greek Lyceum Grade 1 / Physics / Curriculum
Ευθύγραμμη κίνηση: structured theory, worked examples, answered practice, and a mastery checklist for Greek Lyceum Grade 1.
Unit
The essential chapter ideas in a clear sequence before practice.
Choose the body or system, define a positive direction, and mark every force or motion quantity before writing an equation.
A free-body or motion diagram comes before the law. Use resultant force to connect interaction and acceleration.
Vector quantities depend on direction. Keep signs consistent and check that the final unit matches the requested quantity.
Physics
Follow the method step by step and check why every step is valid.
Velocity changes from 5 m/s to 17 m/s in 6 s. Find the average acceleration.
Physics
Learn force diagrams, axis choice, units, and the transition from physical picture to equation.
The structure follows the official textbook layout and is used to organise study.
The areas that usually create mistakes or need extra revision.
a = 2 m/s²
Before calculating, explain the key idea from “Θέση” and which conditions must be checked.
The answer should show not only which rule is used for “Θέση”, 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 “Θέση”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Θέση” to a physical law or model, correct units, and an interpretation.
2. Solve an application and show every intermediate step for “Μετατόπιση”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Μετατόπιση” to a physical law or model, correct units, and an interpretation.
3. Compare a correct and an incorrect approach and justify the difference for “Διάστημα”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Διάστημα” to a physical law or model, correct units, and an interpretation.
4. Create a short exam-style question and check your answer for “Μέση και στιγμιαία ταχύτητα”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Μέση και στιγμιαία ταχύτητα” 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.
