RESOLUTION OF FORCES Hermosa, Enrique Leo L. Physics Department, Mupua Institute of Technology, Intramuros Manila enrique_leo_hermosa@yahoo.com Abstract The experiment is conducted to solve for the resultant force and the angle of the vector quantity. In order to solve for the resultant and its angle, we used the graphical method and the analytical method and we were able to tell the difference between the two and which is more accurate. Key Words – Resultant Force, angle of the vector quantity, Graphical Method, Analytical Method Introduction Vectors and scalar are both considered to be physical quantities. The difference between the two is that scalar quantities only contain magnitude while vector quantities contain both the magnitude and the direction in a space. The resultant vector is a single vector which is also the same as that of vectors when added or the resultant is the sum of all vectors in a space. The vector that balances a resultant is called equilibrant. The equilibrant is equal in magnitude with the resultant but oppositely directed. Equilibrium is a state of balance. When equilibrium is at rest, it is called as static equilibrium. The first condition of equilibrium states that the sum of all forces acting on a system is zero. In this experiment, we used two methods in finding the resultant and its angle. First is the component method and second is the polygon method. By using the component method, the x-component and y-component should be gathered first by using, Fx = Fcos Ѳ and Fy = Fsin Ѳ After acquiring the components, we then get the summation of x-components (Σx) and the summation of y-components (Σy). After getting the summation of both components,
