Document Summary
<0, 0> has zero length and no direction any two arrows with the same length and pointing in the same direction represent the. ______________ same vector initial point start point of a vector terminal point end point of a vector equivalent two arrows that represent the same vector are called this. Subtract the components of the initial point from the terminal point. (head minus tail rule) In a parallelogram representation, the two vectors make a parallelogram, the diagonal of which is the sum of those two vectors. They provide a way to represent the direction of any nonzero vector. By using the formula v = < |v|cos , |v|sin > velocity a vector because it has both magnitude and direction speed the magnitude of velocity dot product/inner product u v = u1v1 + u2v2 u u =
