An Investigation To See If Hookes Law Is Or Is Not reliable

Aim:

I am going to explore Hookes Law and produce a conclusion of my own whether or not Hookes Law is accurate

Hookes Law states that the extension of a spring is proportional to the force applied to it.

Prediction:

I predict that Hookes Law is true because we use springs to measure things such as we use the Newton metre to measure newtons this uses a spring and if spring weren’t accurate to the force applied to it we wouldn’t use a Newton metre.

I believe each 100g weight will move the spring in equal or round about additions each time i.e.

Method:

  • For safety measures I will stand up during the whole experiment
  • For fairness I will keep all the above factors a constant and use the same spring throughout.
  • I will go up in 100g intervals every time until I reach a certain point making sure I do not exceed the springs yield point (where the spring is stretched so far it cannot return to its original position it may be slightly over its yield point but this can still affect measurements and can ruin the whole experiment.)
  • I will repeat this experiment 3 times using the same spring as before and going up in the same weight

Conclusion

My graph points I think are quite accurate, steadily rising in a diagonal direction, I have drawn a line of best fit by using that it showed me where some odd results were and also gave a guideline of where I should be and my results were very close to it. I could of gotten better results if I had used 50 g weights instead to give me a wider view of results and even more accurate than what I have now. I think my conclusion is reliable because everything ties together with the initial prediction and even if Hookes Law is not true my results give some good evidence that it possibly exists my conclusion is: true.

    Investigation on whether Rubber obeys Hooke's Rule

    3 star(s)

    The rubber band has a large elastic limit i.e. retains elasticity and returns to its original shape and not suffer permanent distortion. After a large force is applied, the gradient will begin to decrease because the molecules within rubber will not be able to be stretched any further.

  2. Hooke's Law.

    When compressive stress is applied to a spring, the spring noticeably 'shortens', though the actual length of the body material shortens very little. It is due to this special shape of springs that let it do this. The same occurs when tensile stress is applied.

  1. What factors affect the period of a Baby Bouncer?

    * The time for ten oscillations will be recorded. Each oscillation will be measured when the mass passes the set mid-point on the ruler, (which is the position where the spring naturally hangs once mass has been applied, with no additional force).

  2. Physics Investigation on Hook's Law.

    simply drawn an average table of results, which I have also used for drawing my graph.

    and count this as 0g, as after 100g the spring follows Hooke's law according to the results of the preliminary experiment. The graphs also led me into thinking which spring I should use on the main experiment. The type of spring that I will be using in my investigation is

  2. Investigating Hooke's Law into thin wires.

    If this does happen then the wire will become inelastic. But if the force keeps increasing then the wire will eventually snap. While the wire is still elastic the force being exerted should be directly proportional to the extension. As stated in Hooke's Law.

  1. Investigate stretching using Hooke's Law.

    I will need 6 different weight masses. I will then plot my measurements on a graph, as an extension (on the vertical axis) against the weight. To make it a fair test I try to gently add the weight so that the force with which it landed does not alter the results.

  2. Testing Hooke's Law

    Carbon though can form double or even triple bonds. By splitting the double bonds it is possible to link it to other molecules. By splitting the double bond of ethene (C2H4) and joining it to another ethene molecule the polymer poly(ethene), or polythene as it is commonly known is formed.
