Unit
The essential chapter ideas in a clear sequence before practice.
A wave transfers energy and information without net transfer of matter. Distinguish amplitude, wavelength, period, and frequency.
The relation v = fλ connects the medium and the oscillation. At a boundary, source frequency stays fixed while speed and wavelength may change.
Use the normal, angles, and wavefronts. Superposition adds displacements without permanently changing the component waves.
For “Απλή αρμονική ταλάντωση”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Ενέργεια ταλάντωσης”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Ηλεκτρική ταλάντωση”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Φθίνουσες και εξαναγκασμένες ταλαντώσεις όπου προβλέπονται”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Συντονισμός”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
Physics
Follow the method step by step and check why every step is valid.
In a safe test about “Απλή αρμονική ταλάντωση”, the first condition gives 12 units and the second 9. Which is greater, and what should be kept the same?
The first value is greater by 3 units. A fair test changes only one factor.
Explain “Απλή αρμονική ταλάντωση” in your own words and use a picture, objects, a table, or a simple measurement to support it.
A complete explanation connects the correct idea, a clear representation, and a sensible check.
Ταλαντώσεις
Eight graded tasks from core fluency to exam-style application. Work independently before opening a hint or answer.
Record 7 safe observations about “Απλή αρμονική ταλάντωση” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 7 specific observable or measurable statements, not guesses about cause.
Design a fair test for “Ενέργεια ταλάντωσης”: what changes, what is measured, and which 6 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 6 controlled conditions.
Measurements are 6, 3, and 9 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 9, least 3, difference 6 units.
Sort examples of “Φθίνουσες και εξαναγκασμένες ταλαντώσεις όπου προβλέπονται” into two groups and state the sorting rule.
Each item should clearly match one group.
A full response gives two named groups, at least two examples in each, and an observable sorting rule.
Choose a suitable tool and unit to measure something connected with “Συντονισμός”.
Decide whether you measure length, time, mass, temperature, or volume.
The quantity, instrument, and unit must match, e.g. time-stopwatch-s or length-ruler-cm.
From data 8, 12, 16, predict the next value and explain the pattern.
Look for the constant change +4.
20; +4.
Write 6 safety rules for a simple activity about “Ενέργεια ταλάντωσης” and explain the risk each reduces.
Link each rule to a reason.
A full response gives 6 specific rules, each linked to a risk, and requires supervision where appropriate.
Data A=7 and B=10. Write a conclusion, evidence, and one limitation about “Ηλεκτρική ταλάντωση”.
Do not claim more than the two values show.
B is 3 greater than A. The values support this, but two measurements alone do not prove a general rule.
Ταλαντώσεις
Six distinct assignments from core fluency to challenge, each with an estimated time, hint, and answer guide.
Homework 1: Record 3 safe observations about “Απλή αρμονική ταλάντωση” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 3 specific observable or measurable statements, not guesses about cause.
Homework 2: Design a fair test for “Ενέργεια ταλάντωσης”: what changes, what is measured, and which 2 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 2 controlled conditions.
Homework 3: Measurements are 9, 4, and 13 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 13, least 4, difference 9 units.
Homework 4: Sort examples of “Φθίνουσες και εξαναγκασμένες ταλαντώσεις όπου προβλέπονται” into two groups and state the sorting rule.
Each item should clearly match one group.
A full response gives two named groups, at least two examples in each, and an observable sorting rule.
Homework 5: Choose a suitable tool and unit to measure something connected with “Συντονισμός”.
Decide whether you measure length, time, mass, temperature, or volume.
The quantity, instrument, and unit must match, e.g. time-stopwatch-s or length-ruler-cm.
Homework 6: From data 4, 9, 14, predict the next value and explain the pattern.
Look for the constant change +5.
19; +5.
35 minutes / 30 marks
A timed, full-mark self-assessment with model-answer guidance.
Start the timer when ready, work without notes, show every step, and open model answers only after finishing.

Unit
Curriculum reference sources. Always confirm the teaching sequence with the school and tutor.
Physics
Panhellenic physics requires diagrams, principle selection, equations, units, time management, and chapter connections.
The structure follows the official textbook layout and is used to organise study.
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.
