Newtonian three laws are well-known laws in the classical physics,but why the number of laws should be three could not been well taught in the common classes.In this pa-per,we provide an interesting interpretation for the public understanding of the logical integ-rity for Newtonian three laws.Force is a fundamental concept in Newtonian laws,but it has the same meaning in the inertial and non-inertial frames,which is different from Newtonian laws themselves since they hold only in inertial frame.Inertial force exists only in non-inertial frame and is regarded as fictional,since the origin of the force and its reaction cannot be found.In this paper,when the space-time is introduced to study the inertial force,it can implement the force and can be reacted,so inertial force is real.This provides a novel way to understand force beyond the Newtonian frame(in particular,it means the absolute space-time).
