EXAMPLE

• for a given vector $U=U_1{a}_1+U_2{a}_2+\mathrm{...}+U_n{a}_n$, where $U_1\text{,}{U}_2\text{,}\mathrm{...}\text{,}{U}_n$ are the coordinates of U and $a_1\text{,}{a}_2\text{,}\mathrm{...}\text{,}{a}_n$ are the base vectors, any of the vectors $U_1{a}_1\text{,}{U}_2{a}_2\text{,}\mathrm{...}\text{,}{U}_n{a}_n$,
• the projections of a vector normal and tangential to a surface (normal component and tangential component).

Note 1 to entry: In English, the term "component vector" may be used if "component" is used in the sense of "coordinate" (see Note 2 to entry in IEV 102-03-09).
