Define the system and identify how energy or momentum is transferred. Conservation applies to the correct system and time interval.
Write initial and final quantities before substituting numbers. This exposes losses, external work, and direction.
Energy describes an amount, while power describes its transfer rate. Do not compare systems using work alone when time matters.
For “Έργο δύναμης”, 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 “Κινητική ενέργεια”, 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 “Δυναμική ενέργεια”, 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 “Μετατροπές ενέργειας”, 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 “Διατήρηση ενέργειας”, 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.

In a safe test about “Έργο δύναμης”, the first condition gives 14 units and the second 11. 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 “Έργο δύναμης” 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.
Ενέργεια
Вісім завдань від базових навичок до екзаменаційного рівня. Спочатку виконайте самостійно.
Record 9 safe observations about “Έργο δύναμης” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 9 specific observable or measurable statements, not guesses about cause.
Design a fair test for “Κινητική ενέργεια”: what changes, what is measured, and which 5 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 5 controlled conditions.
Measurements are 8, 2, and 10 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 10, least 2, difference 8 units.
Sort examples of “Μετατροπές ενέργειας” 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 “Διατήρηση ενέργειας”.
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 3, 6, 9, predict the next value and explain the pattern.
Look for the constant change +3.
12; +3.
Write 5 safety rules for a simple activity about “Απόδοση” and explain the risk each reduces.
Link each rule to a reason.
A full response gives 5 specific rules, each linked to a risk, and requires supervision where appropriate.
Data A=9 and B=11. Write a conclusion, evidence, and one limitation about “Έργο δύναμης”.
Do not claim more than the two values show.
B is 2 greater than A. The values support this, but two measurements alone do not prove a general rule.

Homework 1: Record 5 safe observations about “Έργο δύναμης” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 5 specific observable or measurable statements, not guesses about cause.
Homework 2: Design a fair test for “Κινητική ενέργεια”: 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.
Homework 3: Measurements are 4, 3, and 7 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 7, least 3, difference 4 units.
Homework 4: Sort examples of “Μετατροπές ενέργειας” 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.
