Vector Addition. A quick intro on how we can add vectors graphically. Often we need to simplify a system in order to analyze it further. By finding the result of two (or more) vectors, we can simplify the problem at hand. Next. Generally, we will speak of vectors acting concurrently .

Vector Addition A quick intro on how we can add vectors graphically. Often we need to simplify a system in order to analyze it further. By finding the result of two (or more) vectors, we can simplify the problem at hand. Next
Generally, we will speak of vectors acting concurrently. ie. At the same point in space and time. These vectors are CONCURRENT Vector 1, A1 Vector 2, A2 Back Next
Try this: If these were force vectors, predict the direction in which the resulting force (the total force) might be. A1 A2 Back Next
Hopefully you suggested up and to the right – if you did, you’re correct. In this general direction… A1 A2 Back Next
Let’s accurately determine the resultant (the total vector) of these two vectors A1 and A2 by employing a graphical (or geometric means). A1 A2 Back Next
Add the two vectors, A1 and A2, tip-to-tail (or head-to-tail), as per below: The resultant vector is from the original point of concurrency to the head of the translated vector (first tail to last head). Translate one vector from its original concurrent position such that its tail is on the head of the other vector. The resultant R A1 A2 Back Next
Note that in doing this translation, you effectively create a parallelogram, whose sides are the two original vectors, plus the translated version of each vector. This is otherwise known as the parallelogram method of vector addition. The resultant is now from the original point of concurrency to the opposite corner of the parallelogram. R A1 A2 Back Next
So, now you know how to add vectors graphically. Always add head to tail, and draw your resultant vector from an arrow tail to an arrow head – never from an arrow head to another arrow head. For example: DON’T DO THIS..!! IT’S WRONG ! R A1 A2 Back Start
