Particle Velocity in Wave Motion
### Formula
$$v_p=\frac{\partial y}{\partial t}$$
### For Wave Equation
$$v_p=A\omega\cos(\omega t-kx)$$
### Terminologies
- vp → Particle velocity.
- A → Amplitude.
- ω → Angular frequency.
### Conditions / Special Cases
- Particle velocity is different from wave velocity.
### Usage
- Used in advanced wave problems.
