自由运动的物体具有运动和自转的双重性。由于自转惯性的影响,物体的运动轨迹发生弯曲,形成相对的匀速圆周运动,这种匀速圆周运动与外力无关。所以,物体的匀速圆周运动,才是物体的惯性性质。% Freedom of movement object has the movement and rotation of dual nature. Because the rotation inertia effects,object move-ment track happen bending,forming relatively uniform circular motion,this uniform circular motion is not external force cause.So,the object uniform circular motion,is the object inertial properties.
