# The language of Change 1.2

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

$s = \Delta x$

$v = \frac{s}{\Delta t} = \frac{\Delta x}{\Delta t}$

.

kinetic energy ~ the amount of the ability of keeping changing an object’s position

$\frac{1}{2} m v^2$ ~ 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.
