学习物理,常常要解释、描述一些现象和规律.要使表述准确到位,关键在于用词.下面列出常见的易混词,供同学们参考. 1.“称”与“秤” 称(动词):测定重力、质量的过程.如要测定某物体的质量就要进行称量. 秤(名词):测定重力、质量的器材.如实验室常用弹簧秤来测量力. 2.“和”与“或” 和:表示联合,两者同时出现、关系等同. Learning physics often explains and describes some phenomena and laws. The key to accurate representation is the use of words. The following is a list of common confusable words for students to refer to. 1. “Speak” and “Scale” (verb ): Determination of the process of gravity and mass. To determine the quality of an object, we must weigh. Scales (nouns): Determination of gravity, quality of the equipment. If the laboratory commonly used spring scales to measure force. 2. “And” and " Or: and: indicates a union. Both occur at the same time and have the same relationship.
