牛顿第二定律是物理学中最重要的物理规律之一,内容和表达式虽然很简洁,但所包含的内涵却非常丰富.在理解和运用牛顿第二定律时,要领会、掌握和注意以下“八性”.一、正比性物体的加速度跟作用力成正比,即加速度与作用力“一荣俱荣,一损俱损”,物体的加速度跟物体的质量成反比, Newton’s second law is one of the most important physical laws in physics. Although the contents and expressions are very simple, they contain very rich connotations. When you understand and use Newton’s second law, you must understand, grasp, and pay attention to the following: “Eight sexes”. First, the acceleration of a proportional object is proportional to the force, that is, the acceleration and force “have a glory and a glory, and a loss is a loss.” The acceleration of an object is inversely proportional to the mass of the object.
