Unit
The essential chapter ideas in a clear sequence before practice.
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 “Kinematics”, 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 “Dynamics”, 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 “Work and energy”, 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 “Energy conservation”, 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 “Momentum”, 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.
A 2 kg body moves at 7 m/s. Find its kinetic energy and momentum.
Ek = 49 J, p = 14 kg·m/s
Before calculating, explain the key idea from “Kinematics” and which conditions must be checked.
The answer should show not only which rule is used for “Kinematics”, but also why it is valid here.
Mechanik
Eight graded tasks from core fluency to exam-style application. Work independently before opening a hint or answer.
A 5 kg mass moves at 6 m/s. Find kinetic energy.
Ek=1/2 mv².
Ek=90 J.
A machine transfers 2400 J in 15 s. Find power.
P=E/t.
P=160 W.
Structure a solution for “Work and energy”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Work and energy”, shows substitution and calculation, and interprets the result.
Identify three uncertainty sources in measuring “Energy conservation” 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 “Momentum” 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 “Collisions in school depth” 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 “Kinematics” 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 “Dynamics” 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.
Mechanik
Six distinct assignments from core fluency to challenge, each with an estimated time, hint, and answer guide.
Homework 1: A 8 kg mass moves at 2 m/s. Find kinetic energy.
Ek=1/2 mv².
Ek=16 J.
Homework 2: A machine transfers 1600 J in 20 s. Find power.
P=E/t.
P=80 W.
Homework 3: Structure a solution for “Work and energy”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Work and energy”, shows substitution and calculation, and interprets the result.
Homework 4: Identify three uncertainty sources in measuring “Energy conservation” 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.
Homework 5: Plan a suitable graph for “Momentum” 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.
Homework 6: Check whether a result for “Collisions in school depth” 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.
