我们认识事物总有一个由浅入深的过程,在这个过程中对具体事物的认识大多是由不完全正确逐渐过渡到完全正确。这对于我们学习物理的同志来说,也不例外,如对“重力”与“重量”的认识就是这样。 “重力”与“重量”这个概念,在初中《物理》第一册就已出现,那时重力和重量已变成一个笼统的概念,只说“重力的大小叫重量,其实质上已把重量当作标量来 We recognize that there is always a process that goes from shallow to deep. In this process, the understanding of specific things is mostly from incomplete and correct to gradual transition to completely correct. This is no exception for our comrades who study physics, such as the understanding of gravity and weight. The concept of ”gravity“ and ”weight“ has already appeared in the first volume of ”physics" in junior middle school. At that time, gravity and weight have become a general concept, and only the size of gravity is called weight. Essentially weighed as scalar
