A helpful, exam-ready resource for teachers & students.

This abridged and structured revision guide is designed to support IB DP Physics students revising A.5 Galilean & Special Relativity by condensing key syllabus content into a clear, accessible format. It provides full topic coverage while simplifying concepts related to frames of reference and relativistic motion, making it suitable for both classroom review and independent study.

Why This Resource?

Covers Every Assessment Statement – Aligned with the IB Physics syllabus to ensure complete topic coverage.

Structured for Easy Review – Information is organised into concise sections for efficient recap and quick reference before assessments.

Interactive & Trackable – Includes digital checkboxes so students can monitor their progress through each concept.

Time-Saving for Teachers – Can be used as a teaching summary, revision handout, or exam prep guide with minimal preparation required.

What’s Inside?

Galilean Relativity – Overview of inertial frames and relative motion under classical assumptions.

Reference Frames – Definitions and comparisons of frames at rest vs moving frames.

Relative Velocity – Core equations and examples of transforming velocities between frames.

Special Relativity Postulates – Einstein’s two postulates and their implications for all observers.

Time Dilation – Concept, equation, and graphical interpretation of moving clock effects.

Length Contraction – Summary of spatial contraction with key formulas and contexts.

Lorentz Factor (γ) – Definition, use, and impact on relativistic calculations.

Relativistic Momentum & Energy – Connections between momentum, energy, and mass at high speeds.

Classical vs Relativistic Predictions – Clear comparisons of outcomes under each model.

Key Terminology – A structured list of essential vocabulary with brief explanations.

This resource is:

Concise & Focused – Reinforces essential ideas in a compact format without unnecessary detail.

Exam-Focused – Covers required IB DP Physics content in an assessment-ready structure.
