Investigation into Hookes Law - investigate the effect of mass on the extension of a spring.

Extracts from this document...


Physics Coursework Investigation into Hookes Law Aim: To investigate the effect of mass on the extension of a spring. Prediction: My prediction is that, as you increase the mass, the extension of the spring will also increase. E.g. the double the mass, the double the extension. So I am saying that the results should be near enough consistent while increasing in the extension until I reach the end of the experiment. I will now support this prediction with some scientific knowledge. Hookes law is when forces are applied to a solid object which can result in extension. Hookes law is also able to predict how a spring (or other stretchable object) when force is applied to it. So this will show extension into the spring after the force is applied. Equipment: The equipment which will be required for the testing of Hookes Law are: * Clamp and Stand * Weights 50grams each * A measuring apparatus (preferable a 1 metre ruler) * Spring Diagram: Fair Test: I will try to keep this a fair test by only investigating 1 variable. ...read more.


I must not overload the spring and apply to much pressure on to the spring and I will be careful in the way I place the weights on to the spring. Method: First of all in this experiment I will need to apply all the equipment correctly and set it up in the way it is shown in the diagram. Then I will measure how big the spring is when there is no force applied on to the spring, then after that we take the measurement of the spring and then I will go up in 50 grams until I reach 400grams of weight on to the spring and the measurements will be recorded into centimetres of the extension of the spring. Results Table: Mass (g) 1st reading (cm) 2nd reading (cm) 3rd reading (cm) Average (cm) Extension (cm) 0 2 2 2 2 0 50 2.6 2.5 2.4 2.5 0.5 100 4.2 4.3 4.2 4.2 2.2 150 6.2 6.3 6.3 6.3 4.3 200 8.3 8 8.1 8.1 6.1 250 9.9 9.8 9.7 9.8 7.8 300 11.9 11.8 11.9 11.9 9.9 350 13.9 13.9 13.8 13.9 11.9 400 16 16.3 16 16.1 14.1 Analysis ...read more.


This could of all had a major effect on the final outcome of the results. Due to my foreknowledge on hookes law it was easy to roughly predict what the results were going to be. This shows my scientific knowledge was correct about on my final outcome by saying that the extension will get bigger when force is applied. Evaluation: My experiment managed to produce some very good results even though my prediction was only half right but the results was supported well by my scientific knowledge. This helped me produce a graph of a good standard with all points near to the line of best fit. The results could have been a tiny bit inaccurate because of the spring making small movement when I measured the extension. If I was to do this experiment again I would give myself more time and I won't just do this in 1 day I will come back another day and repeat it again so my results will be more accurate. Overall I think this investigation was a success because I come out of it with successful results and a well attained graph. Charlie Taylor-Hill ...read more.

    He found that extension is proportional to the downward force acting on the spring. Results Table Length (cm) Mass (g) 1st 2nd 3rd Average Extension 0 2 2 2 2 0 50 2.6 2.5 2.5 2.5 0.5 100 4.5 4.6 4.3 4.4 2.4 150 6.5 6.4 6.4 6.4 14.4 200

  2. I am investigating the relationship between extension and load, therefore testing Hooke's Law.

    The fairness of the test was ensured by taking three readings of extension of the length and a mean was calculated for each weight. The apparatus remained identical throughout the experiment while we changed only one variable, namely weights. Weights were increased systematically in 0.5 N (50g).

    I also have to ensure that as I use plastacine to hold my stretchy sweet firmly on the metre rule, I don't compress it as this will change the cross sectional area of that region and may affect the extension when a force is applied.

    force between those 2 points (which in this case is always 5). Applying this method gives approximate values for the 2.5th and the 7.5th value which hopefully lie very close to the line of best fit (looking at the graphs show that this is quite an accurate approximation).

  2. Stretching Springs/Hookes Law.

    If, however, the molecules are loosely bonded to each other, a relatively small amount of stress will cause a large amount of strain. Below the elastic limit, when the applied force is removed, the molecules return to their balanced position, and the elastic material goes back to its original shape.
