成都理工大学：《大学物理》课程教学资源（PPT课件）第四章 刚体的转动（教学要求）

The gravitational force 2. Newtons law of universal gravitation

The causes of acceleration of a system--The first law of motion states that zero total force exists when the system has a constant velocity; a nonzero total force on the system causes its acceleration

1. The position vector and displacement Let the plane of the two-dimensional motion be the x-y plane of a Cartesian coordinate system
