Quick explanation
Describe extension as the increase in length of an object when stretched
- This point belongs to Forces and elasticity, especially Stretching and deformation.
- You need to be able to describe extension as the increase in length of an object when stretched.
- The key ideas to know are extension.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Stretching and deformation to exam-style questions, flashcards, and revision notes for Forces and elasticity.
Quick student answer
How does extension work?
Direct answer
In Physics, this page helps you answer questions about extension within Forces and elasticity. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are extension and deformation.
Key terms
- extension: The increase in length of an object when stretched.
- deformation: The change in shape or size of an object due to an applied force.
Common trap
Misunderstanding Extension: Extension should be defined as the increase in length from the original length, so students should practice calculating extension by subtracting the original length from the new length.
