Experiment 2: The Addition and resolution of vectors: The Force Table Alma RomeroJune 9, 2018(Lab Partners- Martin Alvarez, George Said, Alex Votypka, Enock Jean)Introduction The purpose of the experiment is to be able to identify all measurable quantities that can be classified aseither a scalar or a vector. A vector has both magnitude and direction while a scalar has only magnitude.TheoryThe equation for any right triangle cosθ=adjecent sidehypotenusesinθ=Opposite sidehypotenuseadjacent side refers tothe side that is adjacent to the angle θ and opposite side refers to the side opposite to the angle θ.The equation for force is F=(mass)(Gravity)where F is the force of the weights that are attached to the strings, mass is the mass of the weights and gravity is the accelerationTo find the magnitude or direction of the vector, we know the distances traveled in the x and y directions, we used the Pythagorean theorem to find the hypotenuse, which is the total distance traveled.A2=A x2+A y2The direction of the vector can be found using one of the following equations.θ=sin1(AyA)θ=cos1(AxA)θ=tan1(AyAx)This way we can find the direction of the vectors.
