Energy conservation, 6 | Energy 5
.
time ~ change
energy ~ the ability of causing change
Assuming
1. a system of one single particle
2. has only kinetic energy
3. and that kinetic energy is conserved.
conservation of energy ~ an object’s potential amount of change of position, measured with respect to its observer’s unit of change, is constant

.
Note:
The above argument has a bug:
If the mass m is constant, the kinetic energy
should be proportional to velocity squared
, instead of velocity
.

.
However, the above argument is still technically correct:
When
is constant,
is constant. In turn, the magnitude of
also remains unchanged.
