《人民日报》整理这些“入门级”的物理知识,你还记得几个?2020-02-27 08:59·缱绻风铃物理定律,是以经过多年重复实验和观察为基础,并在科学领域内普遍接受的典型结论。一些物理定律是由于自然界,时间和空间等的对称性的反映。定律一般都是固定、且不受外界条件干涉的!物理定律有下列性质:普遍,它在宇宙任何地方都适用。绝对,宇宙中无任何东西能影晌它。一般有量的守恒关系。随着新高考政策“6选3”的推行,很多高中在选科的时候,出现了一些有趣的现象,比如在浙沪两地,新高考物理学科竟然意外“遇冷”,“弃物理”成趋势,学界表示很心塞!那些“似曾相识”的物理知识,你还记得吗?“物质的量不是物质的质量”;“平均速率不是平均速度”;……还有物理学上著名的“牛顿力学三大定律”,你还记得多少?是不是你曾经的阴影和恶梦?①. 惯性定律:空间重力场平衡律;②.重力加速度定律:空间重力场变化律;③. 力的相互作用定律:重力斥力对应律;……一起回忆我们高中时学过的物理课,重温一下那些年我们曾经“死记硬背”过的单位、公式、定律吧!敲黑板、划重点!《人民日报》整理这些入门级物理知识,你还记得几个?戳图自测,不会的,请默默转走吧!编辑整理:清风剑客
