The second law, which states that rate of change of object's momentum is proportional to the force exerted upon it is the most practical law. This law is the logical continuation of the inertia law and explanation of Galileo's principle and transformations. Second law gives a prediction to what will happen with the object when a force acts on it: object's velocity will change and object will accelerate (with negative or positive acceleration). In order to understand the meaning of this law, mass is introduced. The mass of the object is a quantitative measure of inertia, which defines amount of matter contained in object. That's why in modern interpretation the second law says that objects acceleration is directly proportional to the magnitude of the total force and inversely proportional to the mass of the object. That's why mass of the object also defines object's resistance to acceleration.
In terms of mathematics, second law can be written as a differential equation:
where F. is force, k is proportionality coefficient, v is objects velocity and m is object's mass.
If a is acceleration is a constant,...
Third law is mathematical conclusion of the law of conservation of momentum (as it can be stated that acceleration is a derivative of velocity and force is a derivative of momentum). Third law states that though forces of interaction are equal, accelerations may be different as masses of objects may be not the same.
Laws of Newton were proved more than 200 years ago on the base of everyday experiments and they serve as excellent approximation to kinematics and dynamics of objects in everyday life. These laws form the basis of classical mechanics, or mechanics of idealized macro world. They can be applied without errors to objects, which have speeds much smaller than relativistic speeds (speeds which are close to the speed of light). But even in relativistic world the form and essence of Newton's laws is preserved if relativistic space transformations are followed. http://en.wikipedia.org/wiki/Newton's_laws_of_motion
Newton's three laws of motion
Third law states that forces, which occur in pairs, are equal in magnitude, but are oppositely directed. Third law is mathematical conclusion of the law of conservation of momentum (as it can be stated that acceleration is a derivative of velocity and force is a derivative of momentum). Third law states that though forces of interaction are equal, accelerations may be different as masses of objects may be not the same.

Isaac Newton Ruba The Three Laws of Motion: Isaac Newton's Greatest Contribution To the World of Science Isaac Newton is a renowned mathematician, scientist, inventor, professor, and public official who influenced the world of science with his extraordinary and brilliant theories on different phenomena in (primarily) the study of physics, astronomy, and optics. Born on the 4th of January, 1643, Isaac Newton's life as a young man in Woolsthorpe, Lincolnshire in England is unremarkable,
It is noted that the corporeal world is the context to which this discussion specifically applies, with particles at the subatomic level not abiding the same principles. That said, a diagram included in the Nave explanation of Newton's laws helps to clarify that which is meant by the above equation.

Newton Sir Isaac Newton Isaac Newton (Bio, N.d.) Sir Isaac Newton is one of the most recognizable names in all of science. He was a mathematician, a natural philosopher, an inventor, an English physicist, and pretty much an all around genius. His work included the study of how light reacts to reflection, formulating laws of universal gravitation and motion, and building the first ever reflecting telescope. Newton arguably contributed more to the science
Moreover, his theories regarding the gravitation were supposed not to have been made possible without the attempts of his predecessors, as Galileo, to understand the world. Thus, Newton's luck may be put on the fact that he has lived in a period of discoveries, and, as he himself stated, he had seen further than other men, it is because he stood on the shoulders of giants. All in all, Newton
Isaac Newton was the greatest and the most influential scientist of all times. Born in Woolsthrope, England on a Christmas day in 1642 Newton was a bright child with an incredible mechanical aptitude. Newton entered the Cambridge University when he was eighteen years of age and soon he mastered the science and mathematical concepts of his time and went on to continue his independent research. It was during this period
Isaac Newton was born in 1642 at Woolsthorpe in England. His father died before Newton's birth and when his mother remarried, she went to live with her husband and left Isaac with her mother. At 12, he was reunited with his mother after the death of her second husband; she desired to turn him into a farmer in order to support the family. Newton was not successful as a farmer and
