Average velocity

Average velocity is the average of an object's velocity over a period of time. The smaller the time span of an average velocity, the closer it is to instantaneous velocity. It can be found by calculating the dispersement of an object by the time taken for that displace to occur.

Average velocity is written mathematically as

${\bar {v}}\equiv {\frac {\Delta x}{\Delta t}}\equiv {\frac {x_{f}-x_{i}}{t_{f}-t_{i}}}$

where ${\bar {v}}$ is the average velocity and $x_{i}$ and $x_{f}$ are the initial and final positions and $t_{i}$ and $t_{f}$ are the initial and final times.
