Newton's Laws, also known as Newton's laws of motion are based on three principles which explain most of the problems posed by the dynamics, particularly those relating to the movement of bodies. Revolutionized basic concepts of physics and motion of bodies in the universe. Thus, Newton's laws help explain both the motion of the stars, like the movements of artificial projectiles created by humans, and all the mechanics of the machines.


Newton's First Law of inertia Law

The first law of motion challenges the Aristotelian idea that a body can only stay in motion if a force is applied. Newton states that:

Every body perseveres in its state of rest or rectilinear uniform motion unless it is compelled to change its state by forces impressed upon it.
Newton's Second Law or Law of force

The second law of motion Newton says


The change of motion is proportional to the driving force printed and occurs according to the straight line along which this force is printed.

Newton's Third Law of action and reaction Law


With every action occurs whenever an equal and opposite reaction: that is, the mutual actions of two bodies are always equal and oppositely directed.
