### Formula

$$P=\vec{F}\cdot\vec{v}$$

### Expanded Form

$$P=Fv\cos\theta$$

### Terminologies

- P → Power.

- F → Force.

- v → Velocity.

- θ → Angle between force and velocity.

### Conditions / Special Cases

Maximum power:

$$\theta=0^\circ$$

$$P=Fv$$

Zero power:

$$\theta=90^\circ$$

$$P=0$$

### Usage

- Used in moving body and machine problems.
