The respective characteristics of problem solution methods of problem in vector mechanics and analy-tical mechanics are discussed with an example. 用一例題說(shuō)明矢量力學(xué)與分析力學(xué)在解題方法中的各自特點(diǎn)。
A shortcoming in the relationship between the potential energy and force in the analytical mechanics textbook is pointed out, and its origin is discussed. 摘要指出了理論力學(xué)教材中分析力學(xué)部分關(guān)于勢能與力的關(guān)系的一點(diǎn)不足之處,具體討論了勢能的表示式。
