hooke's law hypothesis

F el = − k Δ x,). Investigating Hooke’s Law. Many materials obey this law as long as the load does not exceed the material's elastic limit. It should help you understand how to work scientifically. 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. 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. 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. As the mass of the end of the spring increases, the time period for the spring to complete 20 oscillation will also increase. EXPERIMENT 4 HOOKE’S LAW 1. 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. 2.

As the mass increases, the time will also increase. If you're behind a web filter, please make sure that the domains … Mathematically, Hooke’s law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. Hooke's experiment, shown in his own work 'de Potetia Restitutiva' It is a law of mechanics and physics by Robert Hooke. Theory. Theory. 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. 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. 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. Complete the Part 1 "Prediction" exercise on the lab worksheet before you begin the experiment. Hooke’s Law and Simple Harmonic Motion ... Hypothesis. If you're seeing this message, it means we're having trouble loading external resources on our website. I am aware of the requirements of good academic practice and the potential penalties for any breaches. In the first two materials, the correlation was linear and positive. 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. The values in the first column represent the force applied on the body in Newtons [N]. Which proves that, mass is directly proportional to time. Hypothesis. 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., … The most popular law of elasticity is Hooke’s law. Viva Voce. 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. This spring was undergoing plastic deformation. Hooke’s Law Experiment – Results and Analysis. Table 1 represents the data collected when the Hooke’s Law experiment was performed on three different types of elastic bodies. Objectives The main objective of this experiment is to show Hooke’s Law of spring, calculate the total energy absorbing in the spring.
