It is not necessary to distinguish between
inertial and gravitational masses believing that the nature has
chosen them quite proportional to each other by chance, and not
necessary to believe that the nature by chance has chosen the
power of distance in inverse-square forces exactly equal to two,
and not necessary that in trying to define mass (and force) to
become involved in a vicious circle using presupposition of
existence of inertial reference frame which itself requires
pre-definition of mass. Newton's laws of motion are rewritten in a
logical manner. Some primary models are presented as guides for
discovering the essence of known forces. A model for justifying
the force between two electric and magnetic charges, moving
relative to each other, is presented. In fact energy has only one
form: kinetic energy. The law of action-reaction holds completely
and undoubtedly only during the direct collisions of particles.
