Isaac Newton was an English mathematician, astronomer, and physicist who had developed his three laws of motion by the age of 23. He was born in 1642 the same year the Italian astronomer Galileo Galilei died. Galileo’s work helped to influence or set the stage for the development and creation of Newton’s three laws. Newton’s three laws of motion consists of the first law which is the concepts of inertia, second law which is relating acceleration to its cause and lastly the third law which is action and reaction. The laws of motion were interpreted in the most famous and influential book of all time called, “Philosophiae Naturalis Principia Mathematica” created by Newton in 1687. The book was often known as “Principia” used to explain and …show more content…

The only way to change an objects motion is for it to be impacted by an unbalanced force.

Next is Newton’s second law of motion also known as the “Law of Force and Acceleration”. He was the first to recognize the relationship between force and mass in the production of acceleration. This discovery became one of the most central rules of nature that was able to shape the form of physics. The law states; “The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object”. This is usually expressed by the equation Force= mass x acceleration (F=ma). The law also states that the smaller the object the higher the acceleration there will be and vise versa the larger the object the smaller the acceleration will be. The acceleration of an object depends on the net force acted on the object and the mass of the object. If the mass and net force is both doubled then the acceleration will remain unchanged. This law also gives a explanation for why objects with different masses are able to fall with equal/same acceleration. If the object is only acted on by the gravitational force then air resistance is negligible which is called free fall. During free fall the acceleration of the objects also depends on its inertia and uses the equation Force/mass=gravity (F/m=g), g always
