质点基本解释

汉语拼音:zhì diǎn

由实际物体抽象出来的力学理想模型”。在研究物体的运动时,如果只考察物体的整体运动,且物体的大小比其运动轨道的线度小得多的情况下,可把物体看成质点。如研究地球绕太阳的公转规律时,可将地球看成质点,这将使研究的问题大为简化。

质点详细解释

  1. 在说明物体运动状态时,如果不考虑物体的大小,认为物体只是具有质量的点,这种点叫做“质点”。各种基本粒子体积极小,亦称“ 质点 ”。

    清 谭嗣同 《以太说》:“任举万物中之一物,如一叶,如一尘,如一毛端,如一水滴,其为物眇乎其小矣,而要皆合无量之微质点黏砌而成。” 章炳麟 《菌说》:“即如光、热、电三者,虽不能得其质点,而终与湛然不动者有殊。”
