Paper 1 · Higher combined
Spec reference: 4.3.2 (subtopic).
What you need to know
- Energy Stores
- Movement Energy
- kinetic energy = ½ x mass × speed²
- E = ½mv²
- When something is off the ground, it has gravitational potential energy
- gravitational potential energy = mass x gravitational field strength x
- height
- E = mgh
Self-assessment (checklist)
- I can describe where energy is stored inside a system.
- I can give a definition for internal energy.
- I can explain how heating affects the energy stored
- I can explain the effects that heating can have on a
Key steps (method)
- Identify what the question is testing and use the correct equation/definition.
- Show substitutions and units clearly.
Common mistakes
- Unit conversions, rearranging errors, or quoting a law without applying it.
