The Law of Inertia: An object having an inertial state of being at rest
in uniform motion remains at rest or in uniform motion until acted upon
a force. [1, 2]
1. A force, a form of matter/energy, is a push or a pull which causes
accelerations and decelerations.
2. Only a force can cause a change of the inertial state
of an object comprised of matter and/or energy.
3. The observation of a change of inertial state implies its cause to
a force of some kind.
The Law of Inertia and its Corollaries are fundamental to physical
phenomena at all physical scalar levels, including the scalar level of
quantum mechanics, QM.
Causality, objects and events
comprised of matter/energy as causes causing as effects (A) changes of
the inertial states of pre-existing objects and events or (B) new
objects and events, is the basis of determinism.
Although scientists may not yet be able to observe the changes of the
inertial states of pre-existing atoms and subatomic particles, they are
able to observe the changes of inertial states of percentages of atoms
and subatomic particles in known quantities of atoms/subatomic
particles, then by Corollary 3 of the Law of Inertia this observation
is proof that a force of some kind has caused the observed change of
inertial states, and, thus, determinism is occurring at atomic and
subatomic scalar levels, including QM scalar levels.

As is well known, the fundamental law of the mechanics of
which is known as the law of inertia, can be stated thus: A
far from other bodies continues in a state of rest or of uniform motion

The fundamental law of physics is the law of inertia. "A
keeps the same state as long as there is no cause to change its state."
is, it remains at rest or continues the same kind of motion—that is,
with the same velocity in the same direction—until some cause changes
and such cause we call a 'force.' " [Quotes in the original, but not
This is really not merely a law of physics, but it is the fundamental
of logic. It is the law of cause and effect: "Any effect must have a
and without cause there can be no effect." This is axiomatic and is the
conception of all knowledge, because all knowledge consists in finding
cause of some effect or the effect of some cause, and therefore must
that every effect has some cause, and inversely. [Quotes in the
