The world we live in and interact with is well described by Newtonian Physics. Also called Classical Mechanics it is able to model and explain the behavior of objects in everyday scenarios such as baseballs flying through the air, a child playing on a trampoline, raindrops falling from the clouds, a tow truck pulling a car uphill, the collision of two billiard balls and so on. It can also handle the motion of astronomical bodies such as moons orbiting around a planet, planets orbiting around stars and stars orbiting around the center of a galaxy.
