... same through out the experiment: * The Thickness of the spring * The length of the spring * The material of the spring The things that will vary throughout the experiment will be the mass and the extension. But I will only investigate and ...

... in y change in x Gradient = a = F ?? x b = elastic limit - deformed permanently c = Energy stored this can be worked out by using:- E = 0.5Fx ==> Area of a right angled As the extension increases from the load ...

... K x g (Spring Stiffness is also measured by the gradient of the graph) Where : T = Periodic Time (s) K = Spring stiffness G = Acceleration due to gravity (m/s) This means that K is the spring stiffness (or spring constant), F is ...

... used to this will be used to connect other apparatus in to one place. This will put the spring a good distanced up to prevent the spring from coming in to contact with the table which it will be on. ...

... bend without any weights on it this is due to its own weight, this can be counted as a systematic error .Now I am going to start adding 100g weights to the ruler. The weights will be added from 100g ...

... can be calculated by dividing the modulus of elasticity by the length of the spring. All springs have a different spring constant and the higher the spring constant, the lower the extension. Two springs put into series have a different ...

... is the same distance of an average arms length. Also we can get 10 readings of results from a 1metre length of metal wire if each reading is taking every 10cm. * Factors that affect resistance: Heat (temperature) Area Material Length * Which of these variables ...

... the spring will stretch for the single spring. The opposite of this happens when the springs are in series. When springs are in series, they are extended as normal as if they were single springs, so two single results will ...

... parallel to each other and can stretch up to ten times its original length. Extra force will make the rubber band break. If the rubber is not stretched to breaking, once the force is removed the molecules tend to curl ...

... A spring with a low value for k is weak and a spring with a high value for k is strong. Weak springs are very sensitive and can be used for measuring small forces. Strong springs can withstand larger forces. Preliminary To ...
