... snap and the stand could fall. To prevent these factors from dangers I shall wear goggles and make sure the stand is supported on both sides. Fair test: To make sure that I will get the most accurate results possible I will ...

... rule starting from the bottom of the spring to measure extension in mm. I will then add weights to the spring and measure extension. Before deciding on the range of experimentation I carried out a preliminary test to find the elastic ...

... that different parts of that body are pushed in towards the centre of the body. In most materials, the intermolecular force of repulsion acts against these external forces, so that when the distorting force is removed, the molecules return to ...

... plotted (spring stiffness against load) shows that the stiffness of the spring halves when there is single spring but when two are put in series then the stiffness is doubled. It can be seen clearly that the gradient of single ...

... list of equipment, which I will need to carry out this experiment: - * Retort stand * Clamp * Boss * Springs (4) * Hanger * 1N weights (5) * Metre ruler * Safety glasses Diagram Method 1. Set up equipment as shown 2. Put on safety glasses in case any springs ...

... the load" Equipment List: -springs -weights hanger -Newton weights -stand -clamp -boss -meter ruler Please look at the equipment list and set up as shown in the diagram. I would measure the extension of each spring in series and individually. I would record my results in a table. I will ...

... cord originally away from the length of the cord after more weight has been added onto the end. Some background information: Hooke's law: Hooke found out that extension is proportional to the downward force acting on the spring: Hooke's Law: F=ke F = ...

... are the number of times I tested the rubber band/plastic bag/ spring. Average = The numbers in columns named 1 +2 are added together then divide the answer by 2. Extension = The numbers in the average column take away ...

... me the best results. I can now decide on the thickness of the ruler to use by putting two or more rulers on top of each other to get different thicknesses: Thickness Sag (mm) 1 150 2 90 3 50 From this graph I can see that I need to ...

... is not adequate for earthquake foci to be located and therefore it must change from a rock that can be easily fractured to a less easily fracturable rock. When an earthquake occurs, it produces waves that radiate out from the epicentre ...

... then add a 100g (1 Newton) weight to the elastic band. I will then measure the elastic band and record the size. I will then repeat this with a 200g (2 Newtons) weight. I will repeat the experiment for every ...

... against power to get a strong inverse relationship. Then to plot a graph of power against 1/distance this should then give a straight line and hopefully proportionality that is what I wish to prove. To prove that power produce by a ...

... spring is still and it will stay in the same position for every weight. Diagram Method * Set up all the equipment as shown in the diagram * Add chosen weights to the spring * Record you results I will need to take the readings for ...

... that as the as the length of the block grows (L), the Lateral displacement grows as well. This is because the glass block drags the ray of light towards the normal. This means that the more that there is that ...

... = force in Newton's, k = spring constant and x = extension in metres. I also believe that the amount that my metre rule will bend shall be quantitative. By this I mean that if the load doubles, so will ...

... there is greater force acting on the spring. The data I collected from my preliminary work can help me to predict that if the number of springs doubles the average extension per spring will also double. I found out that ...

... states that frequency is directly proportional to energy. When rearranging the first formula to display frequency as the subject of the formula, and then substituting the value for frenquency given (wave speed/wavelength) into the second formula, we get: Planck 's constant x ...

... taking away the natural length of the spring from the result. * Between O and E the graph is a straight line, which shows that, the extension increase is proportionate to the stretching force up to T (the elastic limit). This ...
