Planar motion of a mass particle is shown in the figure with respect to both a body-fixed frame and an inertial frame. The polar coordinates r, θ are used for the inertial description. A reduced bond graph fragment for planar motion is also shown in the figure. From classical dynamics, the absolute acceleration in r and θ directions are

Using the bond graph for planar motion, show that the absolute acceleration is the same as for polar coordinates.
