Investigating Hook’s Law

Hook law is when obeying force length on a spring or any extendable materials. Example is when an extendable material is stretched by using different weight of masses, and it was able to go back to its normal shape, this is when hooks law as being applied. In contrast if the spring happened not to go back to it’s normal shape, hook law has been disobeyed. This could due to the fact that; too many load are placed on the spring. This can damage the spring. Scientifically this is called elastic limit. During this process, force is applied to spring to pull the atom apart in order to make it stretch. The searching could be small because the atoms of solid are tightly packed together.

*Add 1 mass to the previous mass or masses till it’s 10 in total. (As mass has been added to previous mass, measure the extension of the spring at each step)

*Take out the masses to see if the spring obeyed hook’s law. (This is when the spring its in the

Thinking of what might have caused these.

 It could have been caused by the inaccuracy calculation of line range or scale on graph. The reason why think that the anomalous result discovered on graph is caused by inaccuracy calculation of scale on graph, rather than the methods used, is because the method is very considered and well followed. Another evidence that it has nothing to do with the method but graph is because looking at the result on table before it was plotted on graph looks considerable and understandable, but when plotted on graph diversity information is giving. (This is only because they not meeting the line of best fit). So there fore to improve these, the scale line on the graph should be calculated accurately in order for every result to meet the line of best fit.

  1. Hooke's Law.

    Springs are used by us everywhere: in seats, mattresses, cars, toys, and all other sorts of necessary objects and items we encounter in our daily lives. They are normally made from metal, though they can come from plastics, rubber or even glass.

  2. Hooke’s Law

    This tells me to look for the elastic limit when I am doing the experiment. The key factors in my experiment are the weights and the spring. To not get incorrect results, I have to control these factors by putting on the weights gently to the spring.

  1. Physics Investigation on Hook's Law.

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

  2. Stretching Springs/Hookes Law.

    This relationship is known as Hooke's Law after the British physicist Robert Hooke, who first expressed it. However, if the external force is too strong, the material can become permanently deformed, and Hooke's Law no longer applies. The maximum amount of stress a material can withstand before becoming permanently deformed is called the elastic limit.

  1. An experiment to investigate and determine how rubber behaves when tension forces are applied ...

    I will set up the apparatus as shown but firstly conduct a preliminary test to see the expected outcome for the real teat. I am going measure the length of the rubber band and then conduct the experiment, as I will explain below.

  2. Investigation based on Hooke's law.

    10) Repeat this procedure, removing all the Newton weights until only the mass hanger is left. 11) Add a Newton weight on to the mass hanger. 12) Record the extension of the spring against the ruler. 13) Repeat this procedure until 6 Newtons have been placed on the mass hanger.
