Introduction. See our A-Level Essay Example on An Investigation into Hooke's Law - The aim of this experiment is to find out if the amount of weight applied to an elastic or stretchable object is proportional to the amount the object's length increases by when the weight is applied., … Procedure - Hang a spring from a horizontal metal rod. Dan Best Uncategorized November 20, 2017 November 22, 2017 6 Minutes. Hang a spring from the support, add a weight hanger, and place a 200-g mass on it. I am aware of the requirements of good academic practice and the potential penalties for any breaches. phy 113: hooke’s law/springs objective: the objective of this lab was to test hooke’s law by measuring the spring constants of different springs and spring Objectives The main objective of this experiment is to show Hooke’s Law of spring, calculate the total energy absorbing in the spring. Attach a mass hanger directly to the bottom of the hanging spring and record the position of the bottom of the mass hanger relative to a meter stick. If the applied force (mass) is to remain the same while the vertical displacement is increased, there period will remain the same. However, in the third spring, the correlation was non-linear but also positive. 1. Using Tracker as the timer and timing 10 periods usually yields an accuracy comparable to that of k in the original experiment for linear springs. As the mass increases, the time will also increase. Reference. Method 1. If you're seeing this message, it means we're having trouble loading external resources on our website. Verification of Hooke's Law. Complete the Part 1 "Prediction" exercise on the lab worksheet before you begin the experiment. 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. Hooke’s Law Experiment – Results and Analysis. Viva Voce. Materials Required - A spring, a measuring ruler and weights. If you're behind a web filter, please make sure that the domains … This is in accordance with the derived equation T = 2π (M / k) 0.5. Investigating Hooke’s Law. The spring constant is a coefficient of proportionality between elastic force and displacement, according to Hooke's Law (equation 1. 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—that is, =, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. The modern theory of elasticity is a generalized variation on Hooke's law, which states that the strain/deformation of an elastic object or material is proportional to the stress applied to it. Theory. Hooke's experiment, shown in his own work 'de Potetia Restitutiva' It is a law of mechanics and physics by Robert Hooke. In the first two materials, the correlation was linear and positive.

Introduction In 1660, Hooke’s law was discovered by Robert Hooke, a scientist from England. The second, third and fourth column represents the extension of the bodies after the application of force on the material 1, material 2 and material 3 respectively. That is: F = kdx, where k is a constant factor characteristic of the spring: its stiffness, and x is small compared to the total possible deformation of the spring. The next lab (immediately after Hooke's law) in my lab course is usually the simple harmonic oscillator, where the hypothesis is basically the formula for the SHO period, using the previously measured spring constant. Hypothesis. Hooke’s Law and Simple Harmonic Motion ... Hypothesis. This is because in newton;s second law which is F = ma, if the acceleration is being derived with the presence of time in its formula, it will be F = m(v-u)/t. Of course, this hypothesis … The most popular law of elasticity is Hooke’s law. It should help you understand how to work scientifically. EXPERIMENT 4 HOOKE’S LAW 1. This theory of elasticity says the extension of a spring is proportional to the load applied to it. 2. This is an example of a common experiment used to investigate Hooke’s Law. I was asked to carry out an experiment to prove Hooke’s Law by means of investigating the behaviour of elasticity of three different materials. As performed in the lab. Both the springs were still obeying Hooke’s Law. Many materials obey this law as long as the load does not exceed the material's elastic limit.
