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.

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

    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.

    = 22 / 7 (remains constant), k = spring constant (stiffness, which also remains constant) m = mass (grams) (for graph (iii) ), it was clear that there appeared to be a perfect correlation between an increase in mass and an increase in extension of the spring (being circa 3cm), (positive linear correlation).

    I would also create another graph to show load vs. tension. This would show the relationship in how the load would affect the tension and so this would be useful as I could again use it in my analysis to help me explain my predictions.

  1. The Stiffness Of Springs

    After that I will do the same for springs in parallel i.e. putting 2 springs in parallel, 3 springs and then four springs. The spring I am going to use in this experiment are quite cheap springs, therefore they probably wont have the same spring constant so I wont be able to use the same spring constant for each spring.
