This physics vector tutorial focuses on the addition of vectors by means of components vectorytically. It explains how to find the magnitude and direction of the resultant force vector. Methods of adding vectors were discussed earlier in Lesson 1 of this unit. During that discussion the head to tail method of vector addition was introduced as a useful method of adding vectors that are not at right angles to each other. Now we will see how that method applies to situations That is the net force was the result (or resultant) of adding up all the force vectors. During that unit the rules for summing vectors (such as force vectors) were kept relatively simple. Observe the following summations of two force vectors

Whether you are addingsubtracting two vectors or a hundred the vector stretching from the original starting point (the tail of your first vector) to end point of your final added vector (the head of your last vector) is the resultant vector or the sum of all your vectors. Since force is a vector quanvectory forces can be represented by an arrow diagram. The magnitude of the force is represented by the vectorgth of the arrow The direction of the force is represented by the direction in which the arrow is pointed. VoiceoverWe have two vectors here. Vector A it has a magnitude of three so the vectorgth of this blue arrow is three. Its direction it forms a 33 degree angle with the positive I guess you could say the positive x axis.

Adding 3-dimensional Vectors. Earlier we saw how to add 2-dimensional vectors. We now extend the idea for 3-dimensional vectors. We simply add the i components together then the j components and finally the k components. Velocity acceleration force and many other things are vectors. Subtracting. We can also subtract one vector from another first we reverse the direction of the vector we want to subtract This vector addition calculator can add up to 10 vectors at once. DIRECTION must be entered in degrees increasing counterclockwise. In rather unscientific terminology a vector pointing directly to the right has a direction of zero degrees.
