Terminale Physics — Sociology and Economics (SE): Energy, Society and Radioactivity

Terminale Physics — Sociology and Economics (SE): Energy, Society and Radioactivity

Eight lessons teach selected work, mechanical energy, energy forms, sources/pollution and radioactivity ideas from the final-topic reference. Supplied tariff, supply and emissions models are contextual enrichment, not official syllabus requirements. Reference year: 2025–26. Official 2026–27 alignment has not been verified. This bounded independent study course is not the complete school programme or a guarantee of official-exam readiness.

Who this is for

• Terminale SE learners studying physics in English
• Learners revisiting the stated topics through written explanations and original paper-based problems

Before you begin

• Rearrange one-step equations and use percentages
• Read kg, m, s, N, J, W and basic graphs; units are reviewed
• No calculus required

Outcomes

• Build signed work and mechanical-energy accounts
• Compare power, energy and efficiency for equal service
• Use supplied source and pollution data with clear boundaries
• Interpret nuclear numbers, decay types and half-life evidence

Included

• Written self-paced lessons and worked examples
• Original practice with explained keys and topic checks
• A 12-question single-choice practice quiz
• A paper-based capstone with explained marking guide
• Compact revision reference and exercises

Scope boundaries

• Annual-plan chapters on stimulated nuclear reactions (fission/fusion) and applications/dangers of radioactivity are not taught as full units.
• Full national-textbook detail, variable-force mechanics, dose calculations and complete exam preparation are outside scope.
• Videos, live tuition, laboratory access, certification or official endorsement
• Real-world electrical, radiation or hazardous mechanical activities

Course outline

1. Work and mechanical-energy accounts
   • Work: identifying the force that transfers energy
   • Mechanical energy: accounting for motion and height
2. Forms, power and efficient service
   • Forms of energy and useful transfer chains
   • Power, efficiency and an electricity bill model
3. Sources, supply and pollution
   • Energy sources: reading a supply comparison
   • Pollution and fair comparisons per unit of service
4. Radioactivity and quantitative claims
   • Radioactivity: nuclei, radiation and evidence
   • Half-life: interpreting repeated halving responsibly

The compact revision pack is a selected study companion. It does not replace the taught lessons or the national textbook.
