Answers to AQA GCSE Linear and non linear force-extension graphs
Practice Questions
1.Describe the difference between a force extension graph that is linear, vs one that is non linear.
Linear graph is straight as it follows Hooke’s law.
Non linear graph is not straight, it will be curved as it does not follow Hooke’s law.
2.Is the following graph representative of linear or non linear?
Non linear as it is curved
3. Would the following data produce a graph that is linear or non linear?
| Mass added to spring (kg) | Force, F(N) | Extension, e (m) |
|---|---|---|
| 0.1 | 1 | 0.05 |
| 0.2 | 2 | 0.10 |
| 0.3 | 3 | 0.15 |
| 0.4 | 4 | 0.20 |
