在农业生产当中,有许多生产技术应用了初中物理知识.举例如下:1.摩擦犁地时,常要把犁打磨的很光滑,这样,就减少了犁和土地之间的摩擦,因而,犁起来就省力.拖拉机的外胎做得凹凸不平,以便增大轮子和地面的摩擦,使拖拉机更好地行驶.2.密度
In agricultural production, there are many production techniques that apply junior high school physics knowledge. Examples are as follows: 1. When plowing the ground, the plows are often smoothed so that the friction between the plow and the land is reduced. Thus, the plow It’s effortless. The tires of the tractor are made uneven so as to increase the friction between the wheels and the ground and make the tractor run better. 2. Density
