| Abstract: | Through theoretical analysis,the author holds that the work and energy principle of a partical system,or the change in kinetic energy of an ideal system is equal to the work done by the applied forces,is valid under the condition that the system is both scleronomic and ideal,and not necessarily valid if the system is only ideal but not scleronomic,or an rheonomic ideal system. |
