<P> Newton 's laws of motion are three physical laws that , together , laid the foundation for classical mechanics . They describe the relationship between a body and the forces acting upon it , and its motion in response to those forces . More precisely , the first law defines the force qualitatively , the second law offers a quantitative measure of the force , and the third asserts that a single isolated force does n't exist . These three laws have been expressed in several ways , over nearly three centuries , and can be summarised as follows : </P>
