## 浅析牛顿运动定律的应用与局限

The application of Newton's laws of motion and limitations
Abstract: Newton's laws of motion is the core content of classical mechanics, it has established the relationship between the motion and force of the object, the object of the force and movement. The application of Newton's three laws of problem solving is one of the basic content of high school physics learning, also is one of the important content of college entrance examination, Newton's laws of motion is also the basis of the knowledge of mechanics and electromagnetism knowledge, is a key step to further learn physics well. Newton's laws of motion and its application is one of the study content of calendar year the university entrance exam, is a hotspot of the university entrance exam, but it tends to form changeable, often comes in different colors, flexible examination the students basic knowledge of the use of force and motion ability of solving practical problems. The application of Newton's laws of motion and limitations in our real life also has very extensive application, the written up and reference for the students.

Key Words: Newton's laws of motion; Application; Limitations
