| 单词 | particle |
| 释义 | particle 1(in physics) One of the fundamental components of matter. See elementary particles. 2(in mechanics) A hypothetical body that has mass but no physical extension. As it is regarded as having no volume, a particle is incapable of rotation and therefore can only have translational motion. Thus a real body may often, for translational purposes, be regarded as a particle located at the body's centre of mass and having a mass equal to that of the whole body. |
