The Ballistic Flight Vertical Velocity calculator computes the vertical (y component) velocity in a ballistic flight at a time (t) after launch based on an initial velocity, launch angle, and the acceleration due to gravity.
INSTRUCTIONS: Choose units and enter the following:
Vertical Velocity (Vy): The calculator returns the vertical velocity in meters per second. However this can be automatically converted to compatible units via the pull-down menu.
Thecalculates an object's velocity in the y direction, the vertical component of its ballistic trajectory, at a given time. 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 parallel to the y-component of motion, the is the only affect the ballistic y-velocity. The y-component of velocity changes based on the time and the constant acceleration. The is:
