Jennifer FernandezFebruary 12, 2021TA:Ananya AdhikariPHY2048L-007Experiment 4: Force tablePurpose:I needed to add a set of vectors using the graphical, analytical, and experimental methods to find the resultant vector.Equipment:Force table with pulleyWeight hangersSet of weighted massesStringProtractorCompassRulerBubble levelGraph papersTheory:First we need to know the difference between vector and scalar quantities.Scalar quantities are specified by magnitude alone(time, temperature, mass, etc). Vector quantities are specified by magnitude and direction (force, acceleration, displacement).For vector quantities, it must represented by a top arrow to show force and to represent magnitude it’s the absolute value ofthe force.I need to use different equations to find the components of Fx [Fx=F cos theta] and Fy [Fy=F sin theta] for 3 differentscenarios.To find the direction of the vector I must use Theta = tan^-1(Fy/Fx) and to find the magnitude of the vector I mustuse F= square root of fx^2 + fy^2.For the Component Method, I need to break the vector in to x and y components [Fx=R cos theta & Ry=R sin theta]andthe resultant vector is obtained by adding x and y components [ R= A+B=Rx+Ry].For the graphical representation of the
