Oscillatory motion involves periodic movement around a central position.
- **Simple Harmonic Motion (SHM)**:
- Motion that repeats itself in equal intervals of time.
- x = A sin(ωt + φ) (Equation of SHM).
- **Time Period and Frequency**:
- Time Period (T) = 1/Frequency.
- **Damped and Forced Oscillations**:
- Damped: Amplitude decreases over time.
- Forced: External force drives motion.
**Possible Exam Questions:**
1. What is simple harmonic motion (SHM)?
2. Explain the concept of time period and frequency.
3. What are damped oscillations? Give an example.
4. How is SHM different from random motion?
