Although not always required, we will finish our exploration on reports by analysing the conclusion from the model provided.
In this section, you should summarise your key findings; think of this section as your last chance to remind the reader of what you found. You should not add information that has not been covered in your lab report, but you could include suggestions for future research (or leave them for a ‘Further Work’ section after your conclusion).
Task 9: Read the conclusion section of the lab report we have been looking at and answer the questions:
Conclusion
The elastic behaviour of bungee cord was found to be non-linear for varying applied loads apart from in the range of 2 to 6 N.
At applied loads ranging from 2 to 6 N, the spring constant was found to remain constant at approximately 908 ±0.027 N/m. At loads above and below this range, the spring constant was higher, and the spring-mass system was therefore stiffer.
For an applied mass of 250 g, the measured natural frequency (0.97 ±0.084 Hz) was found to be in good agreement (and within the predicted errors) when compared with the natural frequency predicted using the equation for a spring-mass system with the calculated spring constant (0.96 Hz).

Remember to close your report by listing all the sources that you have used. Make sure that you use the reference system preferred by your department. If you are not sure how to do this, please check the referencing guides in the library.
