82 Work done in lifting a block Equipment: Motion sensor, force sensor, LabPro, laptop, mass set, cage. Part 1: Predictions Imagine you are holding a block of mass 2 kg initially at rest. You then pull upwards, lifting the block by 50 or 60 cm, and end with the block again at rest . 1. Sketch your predictions for the position ( y ), velocity ( v ) and lifting force ( F ) versus time. 2. Make a prediction for the change in kinetic energy of the block. t y t v t F

83 Part 2: Experiment Set-up and calibration First locate and load the experiment file lift_block . To locate the file go to My Computer > Student Shares on svphy01 > University Physics Students > Team Physics 311 > Lab Pro. Connect the Labpro to the computer, a motion sensor to Dig/Sonic 1 and a force sensor to CH1. Be sure that the force sensor is switched to the 50 N setting. Place the motion sensor on the floor with the protective cage over it . Double-click the file to start
