Angle of Velocity with Horizontal

Angle of Velocity with Horizontal

### Formula:

$$\tan\alpha = \frac{v_y}{v_x}$$

### Terminologies:

- α → Angle made by velocity vector with horizontal direction.

- v_y → Vertical component of velocity.

- v_x → Horizontal component of velocity.

### Usage:

- Used to find the direction of velocity of projectile at any point.
