PHY 2048L-019Experiment Date: 9/26/2013Report Due Date: 10/3/2013PURPOSEA set of vectors can be obtained from various calculation methods in order to determine a resultant vector. The current experiment employs graphical, analytical, and experimental techniques facilitating accurate measurements of a resultant force. THEORYThe distinguishing characteristic between scalar and vector quantities lies within the directional component of a vector. A scalar quantity does not include a directional component only magnitude, whereas a vector quantity relates both magnitude and direction by expressing an objects force, velocity, and or acceleration of gravity. A vector is represented by a symbol with anarrow placed directly above it. This is illustrated below. Vector components include xand yunit vectors that are employed while determining the component direction along the xor yaxes. The following equations illustrate employment of vector components to obtain specific vector quantities. F=Fx=Fcosθ,Fy=FsinθMagnitudeofF=F=Fx2+F2Direction ofF=tanθ=FyFxorθ=tan1[FyFx]The parallelogram method, triangle method, and polygon method equate to the graphical representation of a vector sum. Thus, in the above illustration, vectors A and B can be added to equal the resultant vector: A+B=R. A vector sum can also be calculated using an analytical
