$\text { If } \overrightarrow{\mathbf{V}}=\overrightarrow{\mathbf{V}}_{1}+\overrightarrow{\mathbf{v}}_{2} \text {, is } V \text { necessarily greater than } V_{1} \text { and/or } V_{2} \text { ? Discuss. }$
参考答案: The
magnitude of the vector sum need not be larger than the magnitude of either
contributing vector. For example, if the
two vectors being added are the exact opposite of each other, the vector sum
will have a magnitude of 0. The
magnitude of the sum is determined by the angle between the two contributing
vectors.
