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

1 Physics as Natural Philosophy Physics is one of the liberal arts, combining elements of reason, philosophy, mathematics, language, and rhetoric. The term natural philosophy reflects the creative and dynamic interplay that exists in physics among experiment, theory, logic, insight, inspiration, symmetry, beauty, and language
