PHYSICS ANIMATIONS KANNAN . the parallelogram law; the triangle rule; trigonometric calculation; The Parallelogram Law. Or. We also find that vector addition is associative, that is (u + v) + w = u + (v + w ). Graphically we add vectors with a "head to tail" approach. A + B = C = B + A. The parallelogram rule asks that you put the tails (end without the arrow) of the two vectors at the same point, (just the a vector and b vector on the left of the diagram) then it asks you to close the parallelogram by drawing the same two vectors again (the b vector and a vector to the right of the diagram). Let R be the resultant of vectors P and Q. Since PQR forms a triangle, the rule is also called the triangle law of vector addition. Draw the ‘tail’ of vector b joined to the ‘nose’ of vector a. This can be illustrated in the following diagram. Similarly, if you want to subtract both the vectors using the triangle law then simply reverse the direction of any vector and add it to the other one as shown. Applying the triangle's law of vector to triangle OPT. Statement: If two sides of a triangle completely represent two vectors both in magnitude and direction taken in same order, then the third side taken in opposite order represents the resultant of the two vectors both in magnitude and direction. Triangular law of vector addition. Try the given examples, or type in your own (Image to be added soon) Now the method to add these two vectors is very simple, what we need to do is to simply place the head of one vector over the tail of the other vector as shown in the figure below. 10.
