Lab Assignment SheetExploring Springs, Scales, and Hooke’s Law (Week 9)Model or Topic Explored:We will be exploring the Elastic Force Particle, by looking at aclassic example of Hooke’s law, updated using the sensors and advanced datacollection ability of the IOLab unit.You will be determining the spring constant of thespring provided with the unit, or any spring available at home, in this lab using thegraphical and mathematical representations.Name:Date:Observables: The spring will stretchThe spring will bounce backWe will apply force to the iOLab unit, causing it to moveConstants: The springMeasurables: Displacement of the springForce measured by the sensorProblem Statement:How does force depend on displacement ?Prediction: Force will increase in magnitude as displacement increases, they will have apositive linear relationship.Experiment:Procedure:1.Connect the hook eye attachment to the force sensor of your iOLab unit.2.Connect the spring attachment to the hook eye (you may need to secure it to thehook with a string)3.Place the cart (wheel side down) on a flat surface such as a table4.Connect the other end of the spring to a secure (unmoving) object, making surethe spring remains horizontal.
