概要	The direct Kepler problem, which Newton solved for the first time in the human history, is the task to induce physics behind Kepler's first and second laws. Newton broke through the problem by use of classical geometry and novel limiting operations. In this note by use of vector analysis a new passage of the solution starts from Kepler's first law, by way of conservation of the kinematics on the orbits, and arrives at the inverse-square law of gravitation as well as Kepler's second law at the same time. Kepler's first law is revealed essential to generate everything. Kepler's third law, derivative in its nature, is also confirmed within the same formalism.
