Energy conservation, 6.2 | Energy 5.2
.
time ~ change
energy ~ the ability of _keeping_ changing
.
constant velocity ~ the amount of an object’s change of position, measured with respect to its observer’s unit of change, is constant
.
kinetic energy ~ the amount of the ability of keeping changing an object’s position
~ the square of (the amount of change of position, relative to the observer’s unit of change)
.
.
Energy difference is _not_ exactly a measurement of the amount of change, time interval is.
