“生活处处有物理,物理处处有生活。”物理与生活犹如车之两轮,鸟之双翼,相互联系,相互促进。未来,物理学中的任何重大发现与研究,都是建立在生活需要的基础之上。就以我们生活中密不可分的交通工具——汽车来看,处处都有物理的影子。汽车轮胎是圆的,是变滑动摩擦为滚动摩擦,从而减小了摩擦;汽车的方向盘是利用了轮轴的知识,省力;脚踏板是利用了杠杆的知识;汽车的车架要承受很大的压强和高速行驶所带来的摩擦、冲击,就必须利用合理的科学设计。再有,汽车的照明电路采用的并联电路特点和惯性的知识;就连它的发动以水作为冷却剂,都是利用水的比 “Everywhere in life there is physical and physical life. ” The two wheels of physics and life, the wings of birds, are interrelated and mutually reinforcing. In the future, any major discovery and research in physics will be based on the needs of life. As far as our car is concerned, there is a physical shadow everywhere. Automotive tires are round, sliding friction is variable sliding friction, thereby reducing the friction; car steering wheel is the use of knowledge of the axle, labor-saving; pedal is the use of knowledge of the lever; the car's frame to withstand large The pressure and high-speed driving friction, impact, it is necessary to use reasonable scientific design. Again, the lighting circuit of a car uses knowledge of the characteristics of the parallel circuit and its inertia; even its launch with water as a coolant uses the ratio of water
