The extension of the copper wire (in the hooke's law region, at least) is small, perhaps a millimetre or two however, the needle and drinking straw technique magnifies the extension greatly discuss why this method is better than the simple 'flag on the wire' technique. Hooke's law states that the extension of a spring is directly proportional to the applied load (providing the elastic limit has not been exceeded) at a level we express the idea in an equation: we can put this in an equation. A cocco & s c masin 648 the spring (timoshenko, 1953, pp 17-20) this parameter increases as l increases according to the law k = k1 l (2) with k1 a parameter representing the effects on elasticity of all factors other.
According to hooke's law stated above that to extend a spring by an amount dx from its previous position, one needs a force f which is determined by f = kdx here k is the spring constant which is a quality of each spring. Investigate hooke's law essay hooke's law experiment hooke's law: force (newton) = force constant extension of the spring (cm) aim: the purpose of this experiment is to test and verify that hooke's law is correct, which is the extension of a spring is in direct proportion with the load added to it as long as this load does not exceed the elastic limit. Hooke's law, law of elasticity discovered by the english scientist robert hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load. You can investigate hooke's law by measuring how much known forces stretch a spring a convenient way to apply a precisely-known force is to let the weight of a known mass be the force used to stretch the spring.
Investigating hooke's law the short spring because, when i examined my graphs and compared the results of the short spring against the long spring, i found out that the gap between the extensions on the long spring was larger than the gap for the short spring. Hooke's law says that a spring subject to a forcef will stretch an amount proportional to that force: cf , where c is the compliance, a characteristic of the particular spring. 2 experiment 21 purpose the experiment on the hooke's law will help to determine the behaviour of three different elastic materials, and help to investigate the differences of their behaviour around their elastic regions. Virtual hookes law lab - 4physicscom. Hooke's law experiment objective: to measure the spring constant of a spring using two different methods background: if a weight, w = mg , is hung from one end of an ordinary spring, causing.
Prepare the test specimen that is steel bar and find its diameter at tree different places and find its man value mark two points 8 a part of 2 ft long steel bar. Robert hooke was the first to investigate the relationship between the applied force and the extension of the spring and deduced the law for elastic springs called hooke's law in his honor his law expresses a direct relationship between the applied force and the extension of the spring. Hooke's law is a law of physics that states that the force (f) needed to extend or compress a spring by some distance x scales linearly with respect to that distance. Abstract today, you will investigate the relationship between the force applied to a spring and the distance the spring stretches—this relationship is called hooke's law. Hooke's law is the first classical example of an explanation of elasticity - which is the property of an object or material which causes it to be restored to its original shape after distortion.
Hookes-law-g-clamp-experiment-diagram---science-secondarypng this resource is available in standard, eco black and white and super eco colour homepage » secondary » science » ks3 science » physics » forces. Hooke's law investigation - hooke's law investigation introduction - hooke's law is when forces are applied to a solid object and it can result in extension or compression hooke's law is able to predict how a spring (or other stretchable object) would behave when force is applied to it. This website and its content is subject to our terms and conditions tes global ltd is registered in england (company no 02017289) with its registered office at 26 red lion square london wc1r 4hq. Hooke's law program robert hooke 1635-1703(see encarta) to investigate hooke's law not being obeyed, elastic bands can be used to produce a non-linear graph. Included: a powerpoint with examples of hooke's law (including cristiano ronaldo kicking a brick) find someone who activity: this is an activity where pupils are encouraged to go and find someone else in the class who can give them the answer to.
Investigation hooke's law nadja schaeffer - id: 26346796 academic integrity declaration: i am aware of the requirements of good academic practice and the potential penalties for any breaches. Investigating hookes law aim: the aim of this investigation is to find out the relationship between the extension and force applied up to the point of distortion theory: robert hooke discovered a law for all elastic materials in the seventeenth century. Year 7 investigate hooke's law year 7 had a fascinating lesson in physics experimenting on hooke's law which states that the force needed to extend or compress a spring by some distance is proportional to that distance. For a project to investigate hooke's law and to determine the spring constant by an alternative procedure, see the science buddies project applying hooke's law: make your own spring scale share your story with science buddies.
Hooke's law tells us how this spring constant relates to the force we need to apply to stretch the object hooke's law states that the force needed to compress or extend a spring is directly. To investigate hooke's law (the relation between force and stretch for a spring), f = -kx 2 to investigate newton's 3 rd law (law of force pairs) introduction everybody knows that when you apply a force to a spring or a rubber band, it stretches.
