Topics include accelerating and centripetal forces, consequences that follow from the differential equations of motion, the centripetal force and the square of the distance, elliptical orbits of the planet's orbits, the motion of the center of gravity, elimination of dt from differential equations. ambiguities of analytical expression, differential equation for determining the radius vector and more.
