Explanation:
Velocity of a physical object can be obtained by the change in an object's position in respect to time.
Generally, x, y, and z are used in Cartesian coordinates and these are replaced by r, θ, and z.
The unit vectors are er, eθ, and k are expressed in Cartesian coordinates.
The derivatives of the unit vectors are,
The position of the vector and the particle is expressed as,
r =rer +zk
Velocity of the particle is expressed as,
Acceleration of the particle is expressed as,
