7.1Vector Notation

The idea of components freed us from the confines of one-dimensional

physics, but the component notation can be unwieldy, since every one-

dimensional equation has to be written as a set of three separate equations

in the three-dimensional case. Newton was stuck with the component

notation until the day he died, but eventually someone sufficiently lazy and

clever figured out a way of abbreviating three equations as one.

Vectors are used in aerial navigation.
