Hooke’s Law is a scientific law which concerns itself with the elasticity of materials. It states that when a force is applied to a spring, the displacement of that spring will be directly proportional to the amount of force applied . Objectives 1 - Describe how deformation is caused by a force 2 - Describe how the behavior of springs and wires in terms of force, extension and elastic limit 3 - Describe how the behavior of springs and wires in terms of Hooke’s Law and the force constant Equipment Spring with a hook ring stand set of known masses ruler or meter stick

Theory Hooke's law is a principle 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: F = kX , where k is a constant factor characteristic of the spring: its stiffness , and X

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
