Detailed explanation-1: -Summary. The graphical method of adding vectorsA andB involves drawing vectors on a graph and adding them using the head-to-tail method. The resultant vectorR is defined such thatA+B=R. The magnitude and direction ofR are then determined with a ruler and protractor, respectively.
Detailed explanation-2: -The magnitude of the resultant vector (R) can be determined using the Pythagorean theorem. As can be seen in these two examples, the resultant of the addition of three or more right angle vectors can be easily determined using the Pythagorean theorem.
Detailed explanation-3: -Now that we have the skills to work with vectors in two dimensions, we can apply vector addition to graphically determine the resultant vector, which represents the total force.
Detailed explanation-4: -The resultant can be represented graphically by the diagonal of the parallelogram formed by using the two force vectors to determine the length of the sides of the parallelogram. The magnitude of the resultant can be accurately measured as the scaled length of the diagonal.
