Must know

1Distance is the actual path length travelled, while displacement is the shortest directed change in position.
2Distance and speed are scalar; displacement and velocity depend on direction.
3When direction matters, use displacement or velocity. When only total path length matters, use distance or speed.
4Average speed can never be less than the magnitude of average velocity for the same journey.

Formula / process

1Ask whether direction changes or whether the object returns toward the start.
2Distance is the actual path length travelled, while displacement is the shortest directed change in position.
3Write u, v, a, t, and s first, then choose the equation that matches the known set.
4Acceleration measures how quickly velocity changes. The equations of motion connect initial velocity, final velocity,...

Exam traps

1Students often use the same value for distance and displacement in every motion problem.
2Ask whether direction changes or whether the object returns toward the start.
3Would the answer change if the path shape changed?
4Students sometimes substitute into the wrong equation before listing known quantities.

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

1Distance, Displacement, Speed, and Velocity
2Meaning
3One-minute summary
4Path taken
5Start point
6End point

Avoid these traps

1Students often use the same value for distance and displacement in every motion problem.
2Ask whether direction changes or whether the object returns toward the start.
3Draw path and final position separately when comparing these quantities.
4Direction is the turning point between scalar and vector-style answers.

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.

3D visual of distance displacement speed and velocity

DiagramDistance, Displacement, Speed, and Velocity

Distance versus displacement model

Use the labels to connect each part of distance versus displacement to the Grade 9 Physics idea.

Path taken

Used for distance.

Start point

Reference position.

Check: Draw path and final position separately when comparing these quantities.
