Final Velocity in aircraft design refers to the velocity of an object or aircraft at the end of a specific time interval or after a particular event, such as a phase of flight. It is a critical parameter used to assess aircraft performance and behavior during different flight phases. The formula for calculating final velocity and its SI unit are as follows
Final Velocity Formula: The formula for calculating final velocity (vf) is based on the initial velocity (vi), acceleration (a), and the time interval (t) during which the velocity change occurs. It can be expressed as:
- vf: Final velocity, measured in meters per second (m/s).
- vi: Initial velocity, measured in meters per second (m/s).
- a: Acceleration, measured in meters per second squared (m/s²).
- t: Time interval during which the velocity change occurs, measured in seconds (s).
