Key concepts
Why it matters
This objective helps connect Energy stores and systems to exam-style questions, flashcards, and revision notes for Energy changes in a system, and the ways energy is stored before and after such changes.
Quick student answer
What is a system?
Direct answer
In Physics, this page helps you answer questions about a system within Energy changes in a system, and the ways energy is stored before and after such changes. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are system and energy store.
Key terms
- system: A group of objects or a single object that is considered together for the purpose of analysing energy changes.
- energy store: A form of energy that is held within a system, such as kinetic, potential, or thermal energy.
Common trap
Misunderstanding System Definition: Emphasize that a system can include multiple objects interacting with each other, not just one.
