| Abstract: | Solving the problem of simple harmonic vibration and simple harmonic wave have been students＇ learning difficulties in college physics course, because it is difficult to determine the initial phase. If students have mastered the use of the rotation vector method to solve related problems, harmonic vibration can be intuitively and easily researched, which can overcome the difficulties. This paper illustrates the application of simple harmonic motion and plane simple harmonic wave to rotation vector. |
