A metal wire forms the sensing element in a force meter. A technician applies different forces to the wire and records its extension.
| Force in N | Extension in mm |
|---|---|
| 0 | 0.00 |
| 20 | 0.20 |
| 40 | 0.40 |
| 60 | 0.60 |
| 80 | 0.80 |
| 100 | 1.10 |
| 120 | 1.50 |
Explain what the results show about the relationship between force and extension as the force increases.
