SHM as Projection of Circular Motion
### Formula
$$x=A\cos\omega t$$
### Velocity
$$v=-A\omega\sin\omega t$$
### Acceleration
$$a=-A\omega^2\cos\omega t$$
### Terminologies
- A β Radius of circular motion.
- Ο β Angular velocity.
- x β Projection displacement.
### Conditions / Special Cases
- Projection of uniform circular motion on a diameter produces SHM.
### Usage
- Used to derive SHM equations.
