Enter a value for all fields

The **Vertical Position **calculator computes the vertical (y component) position based on an initial velocity, launch angle, and time.

**INSTRUCTIONS**: Choose units and enter the following:

**(V**This is the magnitude of the initial velocity_{0})**(Θ)**This is the launch angle**(t)**This is the time into the ballistic flight.**(h)**This is the initial height above the plane.

**Position (x,y):** The calculator returns the relative position in meters. However this can be automatically converted to compatible units via the pull-down menu.

The **Ballistic Vertical Position** equation calculates an object's position in the y direction, the vertical component of its ballistic trajectory. This is the equation for the ideal projectile, which means it neglects external forces such as air resistance. Since in the ideal projectile motion model the force of gravity is the only force component affecting the trajectory, and the force of gravity is parallel to the y-component of motion, the gravitational acceleration is the only affect the ballistic y-velocity. The y-component of position changes based on the time and the constant acceleration. The formula for the vertical position is:

where:

- y is the vertical position
- V
_{0}is the initial velocity - θ is the launch angle
- t is the time into the flight
- h is the height above the plane
- g is the acceleration due to gravity

- Ballistic Maximum Altitude: This is the maximum altitude achieved in free ballistic flight.
- Ballistic Maximum Range: This is the maximum horizontal range.
- Ballistic Flight Time: This is the time duration of free flight.
- Ballistic Vertical Velocity: This is the vertical velocity at a given time.
- Ballistic Horizontal Velocity: This is horizontal velocity or ground speed.
- Vertical Position (Y) in Ballistic Flight: This compute the vertical position (y) at a given time within ballistic flight.
- Horizontal Position (X) in Ballistic Flight: This compute the horizontal position (x) at a given time within ballistic flight..
- Ballistic Position at Time (t): This compute the position (x,y) at a given time within ballistic flight, where x is distance down range and y is the height above the plane.
- Ballistic Parabolic Equation provides the parabolic flight position equation based on the launch speed, height and angle.
