Document Summary
Mat1339 - lecture 16 - introduction to vectors. Scalar: a quantity that only represents magnitudes (sizes). Vector: a quantity that represents the magnitude and the direction. To turn a vector into a scalar, you need to apply the magnitude. A longer vector will have a bigger magnitude is the direction of the vector a g nitu d e of v e ctor. Parallel vectors have the same direction or the opposite one but possibly a different size. Equivalent vectors have the same magnitude and direction which means that they are parallel and have the same length. You can move vectors without changing the magnitude and direction, it"s called a translation. Opposite vectors have the same magnitude but are in the opposite direction. When you combine two opposite vectors tail by tail, you get a vector direction. with a magnitude 0 in any.
