IP Physics Notes (Upper Secondary, Year 3-4): 6) Work, Energy & Power
Link work to energy transfers, apply conservation for height-speed swaps, and compute power and efficiency in IP Year 3-4 contexts.
Q: What does IP Physics Notes (Upper Secondary, Year 3-4): 6) Work, Energy & Power cover?
A: Link work to energy transfers, apply conservation for height-speed swaps, and compute power and efficiency in IP Year 3-4 contexts.
Quick recap -- Energy tracks the ability to do work. When forces move objects they transfer energy, and the total energy in a closed system stays constant even as it changes form.
The core idea is simple: Work transfers energy when a force moves something.
Use it as a working check: Match the energy store to the situation: kinetic for speed, gravitational potential for height, elastic for springs, and power for energy transferred per second.
Then go one layer deeper: Use the sledge and conservation examples to practise writing the energy pathway, calculating work, allowing for losses, and checking efficiency or power units.
Keep your practice loop tight via our IP Physics tuition hub-it links each topic here to quizzes, diagnostics, and WA-style problem sets.

For Integrated Programme students: Your current school materials, teacher instructions, and assessment scope take precedence because IP topic sequence and depth vary by school. This is an Eclat IP guide, not the O-Level / SEC G3 exam-track guide.
How this chapter applies
- Eclat core: energy stores and transfers, conservation, kinetic and gravitational potential energy, work, power, and efficiency follow Marcus Pang's current Chapter 6 route.
- School-sensitive extension: Marcus identifies internal energy as additional information taught by only some schools. The extension remains at the end of this chapter and is not assumed to be common assessed IP scope.
- Eclat route design: generation-source trade-offs are taught in Chapter 13 beside electrical energy and cost, rather than duplicated here.
- 2027 national comparison: K323 Topic 6 overlaps with the main equations and adds explicit comparison of renewable and non-renewable generation sources. Chapter 13 supplies that comparison inside Eclat's route.
- Check your school: use the energy-store terminology and extension depth required in your current class.
- Exam-track route: use the separate O-Level and SEC G3 Physics notes for K323 topic ownership.
