How the extension of the spring will change or vary, when force is applied.

Extracts from this document...


How the extension of the spring will change or vary, when force is applied. Aim My aim is to see how the extension of the spring will change or vary, when force is applied. The variable in this investigation is the weights. Other possible variables that can be investigated are the different materials of the spring. Fair Test It will be a fair test because the same steel spring will be used on all of them. I will check that it has not reached its elastic limit. I will make sure that while the weights are on the spring, the spring should be still. Equipment Steel spring 8x 1N weights Clamp Stand Meter stick/ruler The measurements that I will need to take are the different lengths of the spring when it has different weights on it. There will be 8 different measurements of the length of the springs. The weights will range from 0.1kg to 0.8kg. The best way to carry out the experiment is to use a stand and attach a clamp to it, you should hang the spring on it and add the weights. ...read more.


I plan to take 8 or 10 readings of the length and weight over a wide range of values. Prediction I predict that if you double the load, it doubles the extension and if you put on 3 times the load it will treble the extension. I predict this due to Hooke's Law. Hooke's law is when: The extension is directly proportional to the stretching force Due to this law I predict that when I plot a graph of showing the extension, it will go up in a straight line. When it reaches its elastic limit then it will curve. Results Table Mass of load Weight of load Initial length of spring (cm) Final length of spring (cm) Extension (cm) 0 0 3.2 3.2 0 0.1 1 3.2 7 3.8 0.2 2 3.2 10.6 7.4 0.3 3 3.2 14.3 11.1 0.4 4 3.2 18 14.8 0.5 5 3.2 21.5 18.3 0.6 6 3.2 25.3 22.1 0.7 7 3.2 28.7 25.5 0.8 8 3.2 33.5 30.3 Graph results The graph shows that the gradient is positive as it is going up. ...read more.


Evaluation I thought that the method I used was quite accurate because I got the right results and I managed to prove Hooke's law. The experiment did not take too long to do. In my results I only had one anomalous result. This was for 8N because I got 4.8 for the extension whereas all the rest were in between 3.4cm and 3.8cm. I think this is becauseit was losing its elastic limit. To make the results more accurate I could put a pointer on the end of the spring so I would be able to read the results more accurately. I should have done each experiment three times and then found the average, this would have been more accurate instead of just doing it once. Even though I did not do these things to make it more accurate, my results were reliable enough. Further work I could use different springs like copper, brass or anything. I would compare the forces required to stretch them and see which spring was the best and which would exceed its elastic limit first. Harpreet Sekhon ...read more.

    the formula: m = y2 - y1 x2 - x1 As the line for which the gradient is being found is a line of best fit, individual points do not nessicarily lie exactly on the line, in order to increase accuracy therefor, I have decided to find the mean value

  2. The Stiffness Of Springs

    This is clearly shown in the graph. I estimate that for 5 springs in parallel the spring constant will be approximately 5 Nm. This will get smaller and smaller. The graph for this looks like a graph for a fraction e.g. y = 1/x. if this is true this graph will continue getting smaller and smaller but never reaching the x axis.

  1. Stretching Springs/Hookes Law.

    The forces of attraction/bonds between the particles stretches because when it stretches it makes the particles separate, so it then after the weights have been removed go back to normal because they are attracted to each other only if the weights that are put on do not make the spring

  2. An Investigation into Hooke's Law - The aim of this experiment is to find ...

    Hypothesis: I predict that I will find that the more weight that is added, the greater the extension of the spring will be. The change in weight will be proportional to the change in the length of the spring.

    The hanger will be connected to the bottom part of the spring. * Also 100g weights will be put on the hanger one at a time. * And lastly one last clamp will be used to clamp the bottom of the stand to the table.

    I do predict though that the extension will be proportional to the tension up to a point where all tensions are applied and the rubber band will suddenly snap. This is because the physical properties of a rubber band are those of which will eventually snap as the tension increases and if the load weighing it down is too much.

    I will have to keep the metre ruler the same at every measurement in case the scale is different, on a different ruler. Also I will need to use the same hanger on each of the sets of parallel springs.

  2. Waves and Cosmology - AQA GCE Physics Revision Notes

    Only photons having energy equal to the difference in energy between two levels can be absorbed by the gas - so only well defined frequencies are removed from the spectrum. Once the electrons have been excited they?re in an unstable state. As they relax into lower states they radiate energy.
