Experiment 6: Vector Addition Monica Molina PHYS 1101 3L2 University Physics I Laboratory Summer 2020 Dr. Aaron Modic June 10-11, 2020
I. Purpose The 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. Theory If several forces with different magnitudes and directions act at a point its net effect can be represented by a single resultant force. This resultant force can be found using a special addition process known as vector addition. In the process of vector addition, each vector to be added is first resolved into components. The components along each axis are then added algebraically to produce the net components of the resultant vector along each axis. This leads to the following: Rx = Ax + Bx = Acos 1 + Bcos 2 Ry = Ay + By + Acos 1 + cos2 Furthermore, the angle q that the resultant R makes with the X axis is given by the following: Angle = ArcTangentRy / Rx
