Each of the examples above involves magnitude and direction.Remember: A vector is not the same as a scalar. (see Part 1 on MiLearn.com) . Scalars have magnitude only. For example, a speed of 35 km/h is a scalar quantity, since no direction is given. Other examples of scalar ...

What are Direction Cosines? In mathematics, a vector is a line segment with magnitude and direction. The magnitude is the size (length) of the vector, and the direction is the orientation of the vector. The vectors are usually constructed using an initial point and a terminal point. ...
