Here is our time independent equation:

There are other popular ways to write the symbols in this equation.

(What follows here, basically, is the same type of discussion that appears in the corresponding section for the velocity equation. An additional note, though, appears here after this section.)

There is more that one symbol for the ** original
velocity**. All three of these symbols cover the same
concept:

v_{o} |
Original velocity |

v_{i} |
Initial velocity |

v_{1} |
First velocity |

And there is more that one symbol for the ** final
velocity**. Both of these symbols mean the same thing:

v_{f} |
Final velocity |

v_{2} |
Second velocity |

Basically, these velocity symbols fall into two families. These go together in one family:

v_{o}, v_{i}, and v_{f}

These go together in another family:

v_{1} and v_{2}

So, using the first family of velocity
symbols, note that **these two equations mean the same
thing:**

Using the second set of symbols, again, we
say the ** same idea with this notation**:

When you write the equation you would ** never
mix** a symbol from one family with a symbol from
another. So, you would

Of course, since this equation is time independent, you can not think of it as a function of time as you could for our other two equations.
