Newton's Law

Newton's laws of motion describe the acceleration of massive particles. The laws may be stated as: the first law otherwise known as the law of inertia which states that "a particle will stay at rest or continue at a constant velocity unless acted upon by a net force", the second law commonly known as the law of resultant force which is stated as "the net force on an object is equal to the mass of the object multiplied by its acceleration", lastly is the third law which is known as the law of reciprocal actions which simply states that every action has an equal reaction.

Newton, who was born in the year that Galileo died, produced a nearly perfect (for the time) response to Galileo's suggestion. Newton's laws provided relationships between the forces acting on a body and the motion of the body. They were first compiled by Sir Isaac Newton in his work Philosophiae Naturalis Principia Mathematica. Newton was inspired by the works of Galileo, so he continued to expound on his studies and even explaining the law of gravity.
