A student compares how a spring and a rubber band stretch.
She applies forces to each object and measures the extension.
The Table shows her results.
Table
| Force in N\text{N}N | 0 | 1.0 | 2.0 | 3.0 | 4.0 | 5.0 |
|---|---|---|---|---|---|---|
| Extension of spring in cm\text{cm}cm | 0 | 2.0 | 4.0 | 6.0 | 8.0 | 10.0 |
| Extension of rubber band in cm\text{cm}cm | 0 | 3.0 | 7.0 | 12.0 | 18.0 | 25.0 |
When the 5.0 N force is removed, the spring returns to its original length. The rubber band is left with an extension of 0.5 cm.
Compare how the spring and the rubber band behave when they are stretched.
Use calculations to support your answer.
