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.
For “Gravity and orbits”, 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 “Stars and galaxies”, 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 “Solar system models”, 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 “The universe introduction”, 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 “Redshift introduction where appropriate”, 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.

Velocity changes from 2 m/s to 14 m/s in 6 s. Find the average acceleration.
a = 2 m/s²
Before calculating, explain the key idea from “Gravity and orbits” and which conditions must be checked.
The answer should show not only which rule is used for “Gravity and orbits”, but also why it is valid here.

An object travels 200 m in 10 s. Find average speed.
v=s/t.
v = 20.0 m/s.
A 7 kg mass accelerates at 2 m/s². Find resultant force.
F=ma.
F=14 N.
Structure a solution for “Solar system models”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Solar system models”, shows substitution and calculation, and interprets the result.
Identify three uncertainty sources in measuring “The universe introduction” and improve each one.
Consider instrument resolution, reaction time, repeats, and controls.
A full response links each specific error source to a targeted improvement and identifies random or systematic impact.
Plan a suitable graph for “Redshift introduction where appropriate” data and explain how to obtain a gradient or relationship.
Put the independent variable on x and dependent variable on y.
A full response labels axes/units, uses a suitable scale and best fit; gradient uses a large triangle and is interpreted with units.
Check whether a result for “Gravity and orbits” is sensible using units, order of magnitude, and a limiting case.
A check should not merely repeat the same calculation.
A full check confirms dimensions/units, compares expected magnitude, and tests behaviour when one variable becomes very small or large.
Connect “Stars and galaxies” to energy conservation or a force/field model and justify the choice.
Define the system and interactions.
A full response defines the system, describes transfer or interaction, applies the appropriate model, and states losses or limitations.
Write a multi-step exam response about “Solar system models” with calculation and evaluation.
Separate givens, model, calculation, result, and evaluation.
A full response includes an appropriate diagram/model, laws, algebraic rearrangement, SI substitution, suitably precise result, and evaluation of assumptions.

Physics
KS3 Year 9: структурований маршрут з математики та фізики з розділами, практикою і наступними кроками.
Структура відповідає підручнику й допомагає організувати вивчення теми.
Теми, де найчастіше виникають помилки або потрібна додаткова практика.
З чого почати: підручник, daily material, PDFs, videos і worked examples.
Цільова практика перед full tests, щоб coverage було зрозумілим.
Як вимірювати прогрес у главі і коли додавати її до загального mock.
Що робити після глави і як вона пов'язана з наступним розділом.
Примітка: офіційну екзаменаційну програму кожного року завжди уточнюйте у школі, викладача та за поточними офіційними джерелами.
