Kinetic Energy can also be determined by taking 'velocity' out of the equation as E = 1/2 mv^2= (ma)d =Fxd . From Einstein's relativity maths,we can know that - 'contraction of 'space' converts 'space' in to time (time dilation) while contraction of 'time' converts 'time' into space.' This indicates that the same entity is changing phase. Since space is expanding, it means that the total potential (magnitude) of time possessed by the universe is decreasing by changing in to space. When the time contained by the universe get's converted fully in to 'space', further expansion of space would 'no more' be possible.
The perception of conversion of time to space 'naturally', through evolution of a mental capacity for dividing distances by a standard of electrical pulse ( eg. NREM sleep wave), gets sensed as 'time'. Along with the perception of direction, the total experience is the perception of 'velocity'. The perception of 'velocity of working' gave sense of power and further, 'power deficiency', sensed as fatigue.
These perceptions are essential for the survival of mobile organisms or organs (eg. to escape from a predator (harm) or reach a source of food or (good) competitively).
