__ Gravity. __ -  As Newton was sitting in his garden, an apple had fell on the ground and he got to thinking why things go straight towards the ground. He thought that the same force that attracted the apple toward the Earth is also what keeps the Moon in its orbit. He then thought, gravity. Newton established that gravity is the force that causes things to fall down.

[|Video Of Gravity] __ Newton's 3 Laws of Motion __ - [|1st]- States that in order for the motion of an object to change, a force must act upon it, a concept generally called inertia.

[|2nd]- defines the relationship between accerlation, force, and mass F = ma

[|3rd]- states that any time a force acts from one object to another, there is an equal force acting back on the original object. __ Calculus. __ -  Used and created by him for the solving of a great variety of mechanical and hydrodynamic problems.

__ Philosophiæ Naturalis Principia Mathematica __ - Latin for "mathematical principles of natural philosophy. It contains the statement of Newton‘s Law of Motion, forming the foundation of classical mechanics, as well as his law of universal gravitation, and a derivation of Kepler’s Laws for the motion of the planets. The Principia is widely regarded as one of the most important scientific works ever written.
