物理是一门与生活密切相关的科学,细心观察生活中的一些现象,同学们就会发现这些现象涉及的问题其实都与物理有关,针对问题我们总会根据生活经验或学过的相关知识作出很多猜想.而要验证这些猜想,聪明的你接下来一定会亲自动手实验吧.科学家的发明、创造也正是经历了这样的一步步探究过程.学过了电阻以后,我 Physics is a science closely related to life, and carefully observe some phenomena in life. Students will find that the problems involved in these phenomena are actually related to physics. For the problems we always make according to our life experience or the relevant knowledge we have learned Many conjecture.And to verify these conjectures, clever you will then personally hands-on experiment.Sciences invention, creation is also gone through this step-by-step process of exploration.After learning the resistance, I
