Let r(t) be a differentiable vector valued function representing the position vector of a particle at time t . Then the velocity vector is the derivative of the position vector.

Let r(t) be a differentiable vector valued function representing the position vector of a particle at time t . Then the velocity vector is the derivative of the position vector.v(t)=r′(t)=x′(t)i^+y′(t)j^+z′(t)k^.(2.5.1)
