能量的概念、能量之间的转化是初中物理教学的一个知识点,尤其电能作为一种应用最广泛的能量,它可以转化为光能、热能、磁能等多种能量形式。我校物理课外活动小组,设计了各种电能转化其他形式能的小实验、小制作——能量魔盒。这个“小 The concept of energy, the conversion between energy is a point of knowledge in junior high school physics teaching, especially as the most widely used energy, it can be transformed into many energy forms such as light energy, heat energy and magnetic energy. Physics Extracurricular Activities Group of our school, designed a variety of small pieces of energy to transform other forms of experiments, small production - Energy Box. This ”small
