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.

    Background Knowledge (looked up some things on Encarta) In my experiment, I am going to be using a spring. I have found that if a material quickly regains it shape after an external force has stretched, bent or compressed it, then it will make a good spring.

    Again, none of these values lie outside of 1.5 x IQR, so I have no outliers in any of my data sets. The standard deviation for this data set is 1.13, indicating that all of the values are precise. The mean of this data is 191.01 and I will take this as my final gradient value.
