Trait
Energy, E, is the confluence of matter and constant motion (i.e., motion that is
constant in terms of the ratio of distance traveled by a mass, divided by the
time to travel that distance, is termed as velocity, v). A trait is an object characterized by its boundary conditions. It is not the point that matter and
motion may be different; rather that matter moving at a constant rate is different than matter not moving. Energy does not move matter. That difference
between matter moving at a constant velocity and matter not moving is
termed as the energy associated with the matter moving at a constant velocity, where E = 1/2 mv 2 (kinetic energy). Energy, E, is also characterized by a
mass moving at constant velocity vector (defined similarly as scalar speed
and direction) as momentum, P = mv. For matter that is not moving, E = 0,
and mass, m, has a defined magnitude that is not equal to zero. Compare the
kinetic energies of a mass moving, first at constant velocity and then at a
constant velocity that is three times greater than that first velocity. The
kinetic energy difference is nine times (due to the squaring of the velocities—one velocity being three times greater than the other velocity), while
the difference in momentum is three times. Motion can be considered to be
limited by the amount of energy that is represented in the moving mass
object, or conversely, the energy that is available for the moving mass object
limits the motion of the mass. As such, motion (or energy) can be construed
as reflective of a boundary condition. Motion of an object is suggestive of
either a limit on the amount of energy (or movement) that is available for
motion or a constraint that is imposed internal to the object that results in
motion. In either interpretation, the mass stays the same. The mass object
and the boundary conditions of the mass object moving have a trait termed
as energy. Neither is energy a property of matter, nor is it an attribute of matter. Energy is a trait of the object called moving (constant velocity) mass. We can
describe energy as a mechanism that can produce a force that causes motion.
Force is also a trait of the object called moving (accelerating) mass. With a constant force, the momentum, mv, increases linearly. Consequently, force and
motion of mass are comparable. Force moves matter.
Force, F, is characterized by an accelerating mass where the motion of
acceleration, a, is constant in terms of the ratio of the distance traveled by a
mass, divided by the time to travel that distance, divided again by that time
to travel that same distance. This difference between an accelerating mass
and a mass that is at rest is what we term as force, where F = ma. Force is the
rate of change of momentum. Mass, as an object, at rest exerts no force due to
motion (which is zero). Consider a mass positioned on a table that is situated
normal to the force of gravity on the Earth’s surface. The motion of the table
is the same as the motion of the mass, both of which are connected to the
Earth through their mutual attractions by the mechanism of gravity (inherent in all matter). The Earth, therefore, all objects, including the table and
mass, are rotating. None of these objects are at rest (in an absolute sense).
