物理知识来源于生活,是人类在不断实践中获得大量经验的基础上形成的,把课堂上的知识应用到生活实践中,才能把物理知识学好、用活。1.多观察,勤思考。实际中的物理问题是错综复杂的,实质是隐蔽的,需要我们仔细观察,认真思考,认识实际问题的物理实质。例如夏日冰棒周围的“白气”;自来水管“出汗”等等,都是我们直接观察到的物理现象,利用物理课上学到的液化
Physical knowledge comes from life and is formed on the basis of a great deal of experience gained by mankind in practice. Only by applying the knowledge in the classroom to the practice of life, can we learn and use the knowledge of physics. 1. More observation, diligent thinking. The physical problems in reality are complex and the essence is hidden, which requires us to observe carefully and think seriously about the physical essence of practical problems. For example, the “white gas” around the summer popsicles; the water pipe “sweating” and so on are all the physical phenomena that we directly observed, using the liquefaction
