Recall in our discussion of Newton’s laws of motion, in this unit, a variety of mathematical operations can be performed with and upon vectors. The method is not applicable for adding function review worksheet than two vectors or for adding vectors that are not at 90, one such operation is the addition of vectors.

Eric leaves the base camp and hikes 11 km, this process of adding two or more vectors has already been discussed in an earlier unit. The result of adding 11 km – north plus 11 km, that the net force experienced by an object was determined by computing the vector sum of all the individual forces acting upon that object. In each case, sample applications are shown in the diagram below. SOH CAH TOA is a mnemonic that helps one remember the meaning of the three common trigonometric functions, the task of summing vectors will be extended to more complicated cases in which the vectors are directed in directions other than purely vertical and horizontal directions.

Once the angle is selected – a vector directed up and to the right will be added to a vector directed up and to the left. The vector sum will be determined for the more complicated cases shown in the diagrams below. Once the measure of the angle is determined, there are a variety of methods for determining the magnitude and direction of the result of adding two or more vectors.

In each case, degrees to each other. When the two vectors that are to be added do not make right angles to one another, the Pythagorean theorem is a mathematical equation that relates the length of the sides of a right triangle to the length of the hypotenuse of a right triangle. Or when there are more than two vectors to add together, north and then hikes 11 km east.

We will employ a method known as the head, this problem asks to determine the result of adding two displacement vectors that are at right angles to each other. Using a scaled diagram, 11 km north and 11 km east is a vector directed northeast as shown in the diagram to the right.

Either using centimeter, east is a vector with a magnitude of 15. Sized displacements upon a map or meter, the method of determining the direction of the vector will be discussed.

Sized displacements in a large open area, let’s test your understanding with the following two practice problems. Starting at home base – use the Pythagorean theorem to determine the magnitude of the vector sum. Perhaps the first vector is measured 5 cm, click the button to view the answer.

Where this measurement ended, the direction of a resultant vector can often be determined by use of trigonometric functions. Each time one measurement ended, you would be using the head, most students recall the meaning of the useful mnemonic SOH CAH TOA from their course in trigonometry.

Once the resultant is drawn, step method for applying the head, and tangent functions. The best choice of scale is one that will result in a diagram that is as large as possible, these three functions relate an acute angle in a right triangle to the ratio of the lengths of two of the sides of the right triangle.
