5 Chapter WebLab#1: "Force and Work" Notebook Section #9 * Go to the following website: http://lectureonline.cl.msu.edu/~mmp/kap5/work/work.htm * Drag the red "brick" vertically upwards and downward with the mouse, and observe how the "energy meter" changes with the motion. * With the brick in the air (not touching the ground), drag the red "brick" horizontally rightward and leftward with the mouse, and observe how the "energy meter" changes with the motion. * With the brick touching the ground, drag the red "brick" horizontally rightward and leftward with the mouse, and observe how the "energy meter" with changes the motion. Questions: 1) What do you notice about the work you do when you lift the object vertically upwards? 2) What do you notice about the work you do when you move the object vertically downwards? 3) What do you notice about the work you do when you move the object horizontally when it is not touching the ground? 4) What do you notice about the work you do when you move the object horizontally when it is touching the ground? 5) How is the work done with vertical motion different than work done with horizontal motion on the ground? 6) Describe a way in which you can do 2 kJ of work while moving a 20-kg mass. Be specific.
