::Andy, Isaac Newton would agree that the exponent would have to be 2 if it's anything. F=ma. Energy is defined as the force times distance, so the units of energy have to be mass times distance squared over time squared. The exponent is fixed because of the definitions of energy and acceleration in classical Newtonian physics. Of course this says nothing about the <i>magnitudes</i> of E, m or v but it does say any other exponent violates Newton's world.
