The Ballistic Angle of Velocity calculator computes the velocity angle of a ballistic projectile at any specific time based on the vertical and horizontal velocity magnitudes.

INSTRUCTIONS: Choose units and enter the following:

• (v_y) Vertical Velocity
• (v_x) Horizontal Velocity

Ballistic Angle of Velocity (α): The angle is returned in degrees.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The Ballistic Angle of Velocity equation computes the angle of the velocity from the local horizontal for an object with input velocity components:

• `v_x` - x-component of velocity
• `v_y` - y-component of velocity
