Introduction

Scott Miller

Forces, Waves and Radiation

Springs

Aim

To investigate which factors affect the length to which a coiled spring stretches when a force is placed upon it, and whether the size of the coils makes any difference to the results.

Prediction

I predict that the heavier the weight placed one spring is, the more it will stretch as the greater the mass, the greater the force of gravity is, pulling the spring. I also think that the bigger the coils are, the less amount of weight the spring needs to stretch to its elastic limit.

Apparatus

  • Wire (plastic coated)
  • Retort stand
  • 30cm ruler
  • Pen (to coil wire)
  • Slotted mass hanger

Method

To perform this experiment, I am going to take a length of plastic coated wire and wrap it around a pen, which will make the wire into a circular spring.

Conclusion

Therefore, my prediction was correct:

“I think that the bigger the coils are, the less amount of weight the spring needs to stretch to its elastic limit.”

Evaluation

I am pleased with the experiment because of the fact that my results were accurate and my prediction was totally correct.

I feel that if I could have improved the experiment, I could have used different types of coils - maybe a tighter one and a looser one - just to further confirm and support my data.

Overall, I am pleased with the how the experiment was carried out and the eventual results.

    There were a few errors in the equipment that I had to take into account. These errors are the systematic errors. My systematic errors were very small so this means that my measurements were accurate. I could have a high random error, as when I carried out this experiment there

    This explains why I don't exact, perfect results. I am now going to quantify these errors. I used 10 ms -2 for gravity instead of 9.81 ms -2. I also used 100 grams as the mass, event though I knew that the masses I used were not exactly 100g each.
