摘要: 在弹簧质量不能忽略的情况下,讨论了串联弹簧振子系统动能和弹性势能表达式,结果表明:串联弹簧的动能不仅与两弹簧自身的质量m1、m2有关,还与各弹簧的劲度系数k1、k2密切相关;串联弹簧的弹性势能只由各弹簧劲度系数和串联弹簧的总伸长量决定.

Abstract: A general discussion of kinetic energy and elastic potential energy of springs in series is made on the occasion that the mass of spring can not be neglected. It turns out that kinetic energy of springs in series is not only related to spring mass ml, m2, but also spring constant kl ,k2, however, elastic potential energy is only decided by absolute elongation of springs in series and their elastic constants.

Key words: energy, springs in series, spring oscillator, spring mass
