How much will a Elastic band stretch after adding weights?

How much will a Elastic band stretch after adding weights.

Prediction

I predict that the more weight added to the elastic band the more it will extend. The reason it extends is because it is elasticised. If I add too much weight it will reach its elastic limit. After that it will not extend and will become plastic. When I take the weights off I think the elastic band will relax to a size slightly bigger then it’s original state. We did a similar experiment with springs instead of an elastic band. The more weight added the longer the spring extended.

The starting length is 11.5cm. Once all the weights have been put on, and then taken off the end size is 13 cm. That is an increase of 1.5cm.

Conclusion

My prediction was correct, the more weight I added the more the elastic band extended. And when I took the weights off the elastic band relaxed to a state slightly bigger then its original size. An increase of 1.5cm. Due to having foreknowledge of Hooke’s law made it easy to roughly predict what the results were going to be.

  1. Determine the value of 'g', where 'g' is the acceleration due to gravity.

    The value that I obtained is 0.020kg, which is close to the value that I should get. Therefore taking into account the error bars on the extension axis were not drawn due to being too small, my value is quite accurate.

  2. An Experiment To Examine the Effect of Springs In Parallel

    * I could use different strengths of springs. Weaker springs would give a greater extension than a stronger one. This experiment, I think, would have been more reliable because I have found that results with little extension are not very accurate. This is because it is harder to measure.

  1. Stretching Springs/Hookes Law.

    point so that it is fair test because if I don't then my results won't be accurate and it won't be a fair test. The important thing about measuring the stretched spring is, if I measure accurately then it will be good, if I don't my results will be wrong

    If it doesn't, it is showing hysteresis. For example, if you place a large force on your fork while cutting a tough piece of meat, it doesn't always return to its original shape: the shape of the fork depends on its history.
