Velocity:
The velocity of a particle or point is described as the rate of change of displacement. Thus, the velocity of point P,

Or V=V x i +V y j+ V z k
Where
Vx = dx /dt → x-component of the velocity
Vy = dy/dt → y-component of the velocity
Vz =dz/dt →z-component of the velocity
and magnitude of velocity
