电能当门的金属球形握把上的静电击中你的时候,你就能感受到电能。运动的电荷形成电流,或者说产生了电能。电器设备,如收音机、电灯以及电脑等,用的都是来自电池或电厂的电能。原子能属于一种势能,储存在原子核中。原子核发生核反应(裂变或聚变)时,就会释放出巨大的能量。目前,核电厂是利用核裂变来发电的,自然核聚变则发生在太阳和其他恒星上。化学能化合物,如巧克力、木头和蜡,都储存有化学能。化学能是指储存在化合物化学键里的势能。你吃的食物、用来点蜡烛的火柴都储存有化学能,甚至你身体的细胞里都储存有化学能。
Electricity You can feel the electric energy when static electricity on the door’s metal spherical grip hits you. The movement of the charge to form a current, or generate electricity. Electrical equipment, such as radios, lights and computers, use electricity from batteries or power plants. Atomic energy belongs to a potential energy, stored in the nucleus. Nuclear nuclear reaction (fission or fusion), it will release a huge amount of energy. At present, nuclear power plants make use of nuclear fission to generate electricity, and natural nuclear fusion occurs in the sun and other stars. Chemical compounds, such as chocolate, wood and wax, store chemical energy. Chemical energy refers to the potential stored in chemical bonds in compounds. The foods you eat, the candles used to light the candles store chemical energy, and even the chemical energy is stored in the cells of your body.
