Hooke’s Law Name: Erin Sullivan Date: 11/2/16 Partners: Brian Drost and Andy Brownell Objective: To determine the relationship (in equation form) between the stretch of a spring and the corresponding force it exerts. Also to decide whether this relationship fits/matches Hooke’s Law, a simple linear relationship that holds for most materials if not deformed too much. In addition, to determine the work done by the spring force during stretching. Sketch: Theory: By suspending two springs and a rubber band (individually) with a certain mass M attached to each we recorded how much the object in question stretched and calculated the force. Using the Δx (stretch) value and the force previously calculated with the values recorded, a graph was generated. The graph helped us determine whether the object obeyed Hooke’s Law or not. By integrating the equation from the graph we were able to find U s , the work done by the spring/rubber band as it was stretched. Also using the graph, we were able to find the work done geometrically by finding the area under the curve.

### What students are saying

• 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.
