解析 C。解析:“Newton's laws of motion are fundamental to our understanding of the physical world. These laws describe the relationship between the motion of objects and the forces acting on them.”,牛顿的运动定律描述了物体的运动和作用在它们上面的力之间的关系。
These three laws form the foundation of what is known as classical mechanics, or the science concerned with the motion of bodies related to the forces acting on it. The bodies in motion could be large objects, such as orbiting moons or planets, or they could be ordinary objects on Earth'...
