Physics: Energy & Power
Topic overview
Work, kinetic and potential energy, power and efficiency, conservation of energy (optional Module 2)
Key concepts
The five modules are verified separately. Math 1 contains no calculus; Math 2 does not require complex numbers, matrices or general differential equations. Each combination reuses module questions and shares them with the special-topic practice; it is for scope-restricted training only and does not represent unseen questions, complete coverage or official difficulty. Please choose modules according to the course you are applying for.
Key points
- ◆Follow the prerequisite knowledge requirements given by the examination body; new concepts may only be used when the question provides sufficient guidance.
- ◆The examples on this site are training with a limited scope and do not represent full syllabus coverage or official difficulty.
