The force needed to extend an elastic object like a metal spring within certain limits is directly proportional to the spring's length. Hooke's law | It's applications and 10 important facts 4.)

It states that the material's deformations are directly proportional to the externally applied load on the material. Repeat the steps 4 and 5 for second spring. ***Your problem in this experiment is to see if the spring on the apparatus obeys Hooke's Law, and find the value of k for your spring.***. PDF Physics 110 Lab 3: Hooke's Law & Oscillations In the elastic limit, the magnitude of the elastic force of the spring is proportional to the deformation of the spring. You can apply a force that stretches or compresses it. Hooke's Law Experiment According to the Hooke's Law: "Within the limit of proportionality, the extension of a material is proportional to the applied force" (Bird & Ross, 2012). Upon further analysis, it can be seen that the gradient for y2 is greater than that of y1 as the value of "a"for the equation of y2 is larger. It states that the force (F) needed to extend or compress a spring by a distance (X) is proportional to that distance. An object is elastic if . A change in length ∆ l is formed. To collect the data, experiment needs to be performed using three different types of materials,material 1, material 2 and material 3. The most popular law of elasticity is Hooke's law. sources of error in kirchhoff's law experiment k = 1/0.016. Excel graphs. Hooke's Law will be verified for a spring and the force constant will be calculated by . Attach any analysis below. The Hooke's Law lab's objective was determine how much force (n) it takes to fully descend a spring to its maximum distance. Mathematically, if an extension xis accompanied by a restoring force Fthen they are related by the equation F= kx (1) If we consider just the magnitude of this expression, we have F = kx (2) In a typical experiment to test this law, one uses several masses hanged vertically 1.
