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