牛顿计算的也是这种离心趋势的大小(他使用的就是conatus 这个词)。至于我们现在认为物体做圆周运动需要一个向心力(centripetal force),是牛顿在后来的著作特别是《原理》中才清晰阐明的。因此,现代历史学家们认为,牛顿的这些手稿表明,尽管在1660年代牛顿写下的公式在形式上与他后...
If none of the parameter variables affect the multibody system, then the multibody dynamics is reduced to a force balance: applied forces must match the net generalized forces determined by the kinematics (that is, inverse dynamics). See @ref implpreskin for more information. @section mocotrap...
Jamie Drake’s natural optimism injects rays of sunshine and positivity into the music, but at their core, these songs come from a place of maneuvering the obstacles, coping through the tough times, learning acceptance, empathy, and understanding. It’s the symbolic opening of a door as a b...
