Vfinal
Vfinal is a shorthand used across science and engineering to denote the final value of a variable V after a process, reaction, or time evolution ends. It is not a standard unit or constant, but a label for an end-state value that is often contrasted with Vinitial.
In mechanics, Vfinal may refer to the final velocity after acceleration or the terminal velocity of an
Notation and usage vary by field: Vfinal is frequently used alongside Vinitial, V(t) for time-varying voltage
