  SAT考试是美国高中生进入美国大学的标准入学考试,包括SAT1和SAT2。SAT2是专项测验,有数学、物理、化学、生物、外语等,大部分为选择题,是可以选科的。今天我们来学习SATII物理专题分析 Multiplication by a Scalar,希望对大家的复习有所帮助。

  Multiplication is like repeated addition. Multiplying 4 by 3 means adding four three times: . The multiplication of a vector times a scalar works in the same way. Multiplying the vector A by the positive scalar c is equivalent to adding together c copies of the vector A. Thus 3A = A + A + A. Multiplying a vector by a scalar will get you a vector with the same direction, but different magnitude, as the original.
