Experiment 6: Vector AdditionMonica MolinaPHYS 1101 3L2 University Physics I LaboratorySummer 2020Dr. Aaron ModicJune 10-11, 2020
I. PurposeThe addition and revolution of vectors experiment was based on finding the resultant vector sum of two or more vectors by methods of vector addition. After performing this experience in the laboratory, we the students were able to complete three steps: Add a set of vectors graphically, analytically to find the resultant, and find out the difference in convenience between using graphical and using analytical method of vector addition.II. TheoryIf several forces with different magnitudes and directions act at a point its neteffect can be represented by a single resultant force. This resultant force can be found using aspecial addition process known as vector addition. In the process of vector addition, each vectorto be added is first resolved into components. The components along each axis are then addedalgebraically to produce the net components of the resultant vector along each axis. This leads tothe following:Rx=Ax+Bx=Acos1+Bcos2Ry=Ay+By+Acos1+cos2Furthermore, the angle q that the resultant R makes with the X axis is given by the following:Angle=ArcTangentRy/Rx
