Online Experiment 3: Vector AdditionLab Group: 13 Sradha Vijayannair Jason Hernandez Phys 2125- 11149 DUE DATE: July 25, 2020
OBJECTIVESWhen a number of forces passing through the same point, act on an object, they may be replacedby a single force which is called the resultant or the sum. The resultant therefore is a single forcewhich is similar in effect to the effect produced by the several forces acting on the body. It istherefore a single force that replaces those forces. The objectives of this lab are to use graphical,analytic and experimental methods to:1. Resolve a force vector into its rectangular components, and2. To find the resultant of a number of forces acting on a body.Since this lab is to be done at home, only the Graphical and Analyticalparts are to be done. Do these on paper, take nice pictures, and uploadwith your report. Parts not to do have been changed to red font.APPARATUS1. Force table5. Strings for suspending the masses2. Four weight holders6.
