Velocity and Acceleration in spherical coordinates-Part 1. Velocity and Acceleration The velocity and acceleration of a particle may be expressed in spherical coordinates by taking into account the associated rates of change in the unit vectors:, spherical coordinates. Recall that such coordinates are called orthogonal curvilinear coordinates. The coordinate system is selected such that it is convenient for describing the problem at hand (boundary geometry or streamlines). Undoubtedly, the most convenient coordinate system is streamline coordinates: V(s, t) v s (s, t)eГ– s (s, t) However, usually V not known a priori and even if known.

Velocity in Spherical Coordinates Top In kinematics, velocity of any particle or any body is given by change in its Position with respect to time. If a particle is moving with some velocity then it means that it is changing its position with respect to time. Acceleration is defined as the time rate of change of velocity. Hence, acceleration in Spherical polar Hence, acceleration in Spherical polar coordinate system is given as,

The position, velocity, and acceleration vectors of a given point can be expressed using these coordinate systems, but we have to be a bit more careful than we do with fixed frames of reference. Since the frame of reference is rotating, we must take the derivatives of the unit vectors into account when taking the derivative of any of these vectors. If the coordinate frame is rotating at a rate of is the velocity potential function. Such that the components of Such that the components of velocity in Cartesian coordinates, as functions of space and time, are
