Every measurement identifies a physical quantity, numerical value, unit, and suitable instrument. A value without a unit is incomplete physical information.
Change one independent variable, measure the dependent variable, and control the rest. Repeats improve reliability.
A graph reveals trends and allows slope or intercept analysis. Uncertainty and anomalous points should be discussed, not hidden.
For “Uncertainties”, 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 “Linearisation”, 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 “Graph gradients/intercepts”, 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 “Risk assessment”, 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 “Evaluation and improvement”, 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.

Length readings are 10.40, 10.30, 10.35 cm. Find the mean and report suitable precision.
Mean ≈ 10.35 cm.
Before calculating, explain the key idea from “Uncertainties” and which conditions must be checked.
The answer should show not only which rule is used for “Uncertainties”, but also why it is valid here.

Readings: 5.0, 5.2, 4.9 cm. Find the mean and half-range uncertainty.
Mean = sum/3; uncertainty = (max-min)/2.
5.033333333333333 cm ≈ 5.03 cm; ±0.15 cm.
Design a valid investigation for “Linearisation” with independent, dependent, and 4 controlled variables.
Include range, repeats, and safety.
Full method: clear variables, at least five values, repeats/mean, suitable instruments, 4 controls, and specific safety.
Structure a solution for “Graph gradients/intercepts”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Graph gradients/intercepts”, shows substitution and calculation, and interprets the result.
Identify three uncertainty sources in measuring “Risk assessment” 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 “Evaluation and improvement” 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 “Uncertainties” 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 “Linearisation” 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 “Graph gradients/intercepts” 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.

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.
