Newton's first law expresses the principle of inertia: the natural behavior of a body is to move in a straight line at constant speed. A body's motion preserves the status quo, but external forces can perturb this. The modern understanding of Newton's first law is that no inertial observer is privileged over any other. The concept of an ...

This and Newton's law for motion (=) are applied to each ball, giving five simple but interdependent differential equations that can be solved numerically. When the fifth ball begins accelerating , it is receiving momentum and energy from the third and fourth balls through the spring action of their compressed surfaces.
Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). [1]
Succinctly stated, Newton's law of gravitation states that the force on a spherical object of mass due to the gravitational pull of mass is = ^, where is the distance between the two objects' centers of mass and ^ is the unit vector pointed in the direction away from the center of the first object toward the center of the second object.

They were first compiled by Sir Isaac Newton in his work Philosophiæ Naturalis Principia Mathematica, which was first published on July 5, 1687. Newton's three laws are: A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force. (This is known as the law of inertia.)
