The Horizontal Velocity calculator computes the horizontal (x component) velocity based on an initial velocity and a launch angle.
INSTRUCTIONS: Choose units and enter the following:
Horizontal Velocity (Vx): The calculator returns the velocity in meters per second. However this can be automatically converted to compatible units via the pull-down menu.
At the instant of launch, before any friction has slowed the launched projectile, the object has a vertical velocity and a horizontal velocity. This calculator computes the horizontal velocity.
The Ballistic Velocity (horizontal) equation calculates an object's velocity in the x direction, the horizontal component of its ballistic trajectory. This is the equation for the ideal projectile, which means it neglects external forces such as . Since in the ideal projectile motion model the is the only force component affecting the trajectory, and the is perpendicular to the x-component of motion, the does not affect the ballistic x-velocity. The x-component of velocity remains constant. The is:
