Quick explanation
Describe energy-store changes when an object is accelerated by a constant force
- This point belongs to Energy changes in a system, and the ways energy is stored before and after such changes, especially Energy stores and systems.
- You need to be able to describe energy-store changes when an object is accelerated by a constant force.
- The key ideas to know are object, accelerated, and changes.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

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
Why does energy-store changes when an object is accelerated by a constant force?
Direct answer
In Physics, this page helps you answer questions about energy-store changes when an object is accelerated by a constant force 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 energy-store and constant force.
Key terms
- energy-store: A form of energy that is stored in a system, which can change when the system undergoes physical changes.
- constant force: A force that does not change in magnitude or direction, applied to an object to accelerate it.
Common trap
Confusing work done with energy stored: Explain that work done by a constant force changes the energy store of the object (e.g., kinetic, potential, or elastic) only if the force acts over a displacement; the amount of energy transferred equals the work (force × distance) and is stored as a specific form of energy, not as a generic ‘energy increase’.
