Quizplus · Accepted Answer

Newton's theory included the concepts of inertia (objects at rest remain at rest, and objects in motion remain in motion), consistent laws throughout the universe, universal gravitation (all objects attract each other with a force proportional to their masses and inversely proportional to the square of the distance between them), and acceleration (the rate of change of velocity). However, crystalline spheres were an idea from ancient Greek astronomy, which Newton did not include in his theory.
