Document Content and Description Below

Objective The objective of this lab is adding vectors using both the tail-to-head method and the component method and to verify the results using a simulator. Theory A scalar quantity is a number ... that has only a magnitude. When scalar quantities are added together the result is a sum. Vectors are quantities that have both magnitude and direction; specific methods of addition are required. When vector quantities are added, the result is a resultant. For example, if you walk 100 m north, then 100m east, you will walk a total distance of 200 m (distance is a scalar quantity). However the displacement Δr is a vector, involves both distance and direction. So, the same 200 m walk results, in a displacement of approximating 141 m northeast of where you began (141 m, northeast of your starting position). A negative vector has the same length as the corresponding positive vector, but with the opposite direction. Making a vector negative can be accomplished either by changing the sign of the magnitude or by simply adjusting the direction by 180°. Suppose you have a vector with magnitude 5 m in the direction of 100° (related to the positive X-axis). You can describe it specifying the magnitude and direction such as ° . Also, you can identify the opposite vector to ⃗ V , which will be - ° or - ° Experiment: Vector Addition. Tail-to-Head Method. Geometric method. Part A. Vectors can be added together graphically by drawing them end-to-end. A vector can be moved to any location; so long as its magnitude and orientation are not changed, it remains the same vector. When adding vectors, the order in which the vectors are added does not change the resultant.  Draw each vector on a coordinate system; begin each from the origin.  Choose any vector drawn to be the first vector.  Choose a second vector and redraw it, beginning from the end of the first.  Repeat, adding as many vectors as are desired to the end of the “train” of vectors [Show More]
