# velocity

Velocity is a vector quantity specifying both the speed and direction of movement of an object in a given frame
of reference. The magnitude of velocity is the scalar quantity speed (*S*), related to distance (*s*) and time (*t*)
by the equation *S* = *s*/*t*; similarly velocity (**v**)
is related to distance and time by **v** = *ds*/*dt*.
Angular or rotational velocity is given by ω = *dθ/dt*.
