1. The focus of the lecture is simple harmonic motion.

2. The system executes simple harmonic motion.

3. Harmonic Motion: experimental board, spring weight , loaded board, counterpoise, stopwatch.

4. A face harmonic motion drive of separate tooth is a new form of utility model drive.

5. The lecture ends with a discussion of simple harmonic motion.

6. Amplitude, frequency and period of simple harmonic motion are also defined in of the lecture.

7. Hooke's Law - Springs - Simple Harmonic Motion - Pendulum - Small Angle Approximation.

8. Their appearance is connected with anharmonicity, which leads to a breakdown of the selection rules derived assuming simple harmonic motion.

9. The balance wheel of a watch is a familiar example of angular harmonic motion.

10. The motion of the balance wheel of a watch is an example of angular harmonic motion.

11. The logarithmic spiral method is a good way of describing damped harmonic motion.
