Must know

1Work, energy, and power connect force, displacement, energy transfer, and the rate of doing work across mechanical...
2Work is done when a force causes displacement, and energy measures the ability to do work.
3Separate scalar work, energy transformation, and power rate while keeping formulas linked to meaning.
4Power tells how fast work is done, not how much work is done.

Formula / process

1Name the energy form before substituting numbers.
2Work, energy, and power connect force, displacement, energy transfer, and the rate of doing work across mechanical...
3Check whether the system is effectively isolated in the interaction interval.
4This topic explains centre of mass, momentum, impulse, and collisions by treating several interacting bodies as one...

Exam traps

1Students often use energy formulas without stating what energy form is changing.
2Name the energy form before substituting numbers.
3Did you say whether the energy is kinetic, potential, or transferred as work?
4Students often conserve momentum in situations where significant external forces are still acting.

Answer frame

Start with the exact keyword or formula before adding explanation.
Use one example, diagram cue, observation, or substitution to support the answer.
For 3 marks: definition, reason, and one supporting point.
For 5 marks: setup, method/process, example, conclusion, and final check.

Exam strategy

Write to the mark pattern

3 focus areas

Practice written answers Chapter test

Likely prompts

1Definition-with-unit questions followed by one reason or example.
2Numerical questions where formula, substitution, and unit carry marks.
3Diagram or process questions: ray paths, circuits, forces, energy flow, or graphs.

Keywords to include

1Work, Energy, and Power
2Meaning
3One-minute summary
4Force acts
5Displacement occurs
6Energy changes form

Avoid these traps

1Students often use energy formulas without stating what energy form is changing.
2Name the energy form before substituting numbers.
3This makes formulas easier to remember with meaning.
4Keep the relation among work, energy, and power explicit.

Answer frame by marks

3 marks

Define the term, write the unit or formula, then add one relevant example.

5 marks

Draw or state the setup, explain the principle, apply the formula/process, and finish with unit or conclusion.

Notes Write answers

3D visual of work, energy, and power showing force, displacement, kinetic energy, potential energy, energy transfer, and power as rate of work

FlowWork, Energy, and Power

Energy transfer story flow

Follow this sequence when writing or checking an answer on energy transfer story.

Force acts

Potential for work appears.

Displacement occurs

Work is done.

Check: This makes formulas easier to remember with meaning.

3D visual of a system of particles and collisions showing centre of mass, momentum, impulse, elastic and inelastic collisions, before-after states, and conservation of momentum

DiagramSystem of Particles and Collisions

Collision reasoning map model

Use the labels to connect each part of collision reasoning map to the core Grade 11 Physics idea.

System

Set of interacting bodies.

Initial momentum

Before collision.

Check: State the system first in collision problems.

3D visual of rotational motion showing a rotating disc, fixed axis, torque, moment of inertia, angular velocity, angular acceleration, angular momentum, radius, and tangential velocity

DiagramRotational Motion

Linear and rotational analogy model

Use the labels to connect each part of linear and rotational analogy to the core Grade 11 Physics idea.

Force

Translational cause.

Torque

Rotational cause.

Check: Analogy tables help organise rotational ideas quickly.

DiagramWork, Energy, and Power

Mechanical energy set model

Use the labels to connect each part of mechanical energy set to the core Grade 11 Physics idea.

Work

Transfers energy.

Kinetic energy

Energy of motion.

Check: Keep the relation among work, energy, and power explicit.
