Suppose a physical quantity needs to be represented in pictorial form...for example distance. Such value represented should have 3 parts - 1)Orientation - Or the angle that it makes to the axes of the Cartesian coordinate system under which things are being observed. In the 2 images below, there's a represented quantity by a line segment, the only different between the 2 is the orientation WRT the axes - http://img221.imageshack.us/img221/3521/orentation2.png [Broken] http://img107.imageshack.us/img107/6857/orentation1.png [Broken] 2)Position - The exact position of the plotted value; if another value only has to differ WRT this vector by position, this value should be moved translational to give the other value. These 2 images below shows difference between the 2 plotted values by virtue of position - http://img395.imageshack.us/img395/1133/position2.png [Broken] http://img221.imageshack.us/img221/3977/position1.png [Broken] 3)Direction - Given the above 2 factors, this one will be left as binary. It actually shows the direction at which the magnitude of a plotted value has progressed in. In the 2 images below, difference lies between the direction solely - http://img240.imageshack.us/img240/6527/direction2.png [Broken] http://img35.imageshack.us/img35/8817/direction1.png [Broken] Are these 3 factors correct? If so, how much does a scalar and a vector define?
