非惯性系下机械能守恒定律
Inquire Into the Law of Conservation of Mechanical Energy in Non-inertial System
【摘要】 从质点组相对运动动力学方程出发,考虑每个质点受到的惯性力,推导出非惯性系的动能定理,并在此基础上对机械能守恒进行研究,给出了惯性力为保守力的条件.
【Abstract】 This paper,on the basis of motion kinetics equation,after considering the inertial force,infers the theorem of kinetic energy in non-inertial system.Based on that,to study conservation of mechanical energy,this paper puts forward the condition of inertial force to be conservative force.
