Drawing Vector Diagrams. Physics Lecture 7. For a pdf transcript of this lecture go to www.richardlouie.com. Vector addition is one of the most common vector operations that a student of physics must master. When adding vectors a head-to-tail method is employed. The head of the second vector is placed at the tail of the first vector and the head of the third vector is placed at the tail of the second vector and so forth until all vectors have been added. The graphical method of subtracting vector B from A involves adding the opposite of vector B which is defined as -B. In this case A B A (-B) R. Then the head-to-tail method of addition is followed in the usual way to obtain the resultant vector R. Addition of vectors is commutative such that A B B A.

Generally when constructing a phasor diagram angular velocity of a sine wave is always vectorumed to be in radsec. Consider the phasor diagram below. Phasor Diagram of a Sinusoidal Waveform As the single vector rotates in an anti-clockwise direction its tip at point A will rotate one complete revolution of 360 o or 2 representing one complete cycle. This physics vector tutorial provides a basic introduction into vectors. It explains the process of vector addition and subtraction using the head to tail method of adding 3 vectors.

Adding and Subtracting Vectors To add or subtract two vectors add or subtract the corresponding components. Let u u 1 u 2 and v v 1 v 2 be two vectors. Then the sum of u and v is the vector Scalars have a size while vectors have both size and direction. When adding vector quanvectories it is possible to find the size and direction of the resultant vector by drawing a scale diagram. To subtract vectors proceed as if adding the two vectors but flip the vector to be subtracted across the axes and then join it tail to head as if adding. Adding or subtracting any number of vectors yields a resultant vector. Key Terms. origin The center of a coordinate axis defined as being the coordinate 0 in all axes. Forces are vectors and as such any operation that can be performed on vectors can be performed on force vectors. The addition of vectors is one such operation. The method of adding vectors graphically and vectorytically is discussed in the context of force vectors.  ## Adding Elements To An Existing Graph

You should now have a graph with three differently-colored line plots. For information on grouping plots see Grouping Data Plots in [more]
