物理命题不能出现科学性错误,这是大家都认同的原则.但是,由于缺乏实验基础、凭空编撰,再加上疏忽大意,在命题中往往会出现这样或那样的毛病.因此,在物理考试命题中必须小心谨慎,现在我把平常发现的一些问题列举几个,供大家借鉴.例1.步枪子弹飞出枪口时的速度为80m/s,沿水平方 There is no scientific mistake in the physics proposition. This is a principle that everyone agrees on. However, due to the lack of experimental basis, out of thin air editing, plus negligence, prone ones or the other in propositions. Therefore, in the physics examination proposition We must be careful, and now I will list some of the issues that are usually found for reference. Example 1. The speed of rifle bullets flying out of the gun’s mouth is 80m/s, along the horizontal
