(209.102.129.71)Re: the two forms of energy in question here. (paul baughn)
Is there any equivalence in the amount of energy contained in a car moving down the road at 100 Km/hr and the amount of energy it takes to overcome friction and so keep it moving at that speed?
If 1/2mv^2=mgh then we can cancel the m's and 1/2v^2=gh. Therefor if you are above the surface of the earth you must have a certain fixed velocity? Nope. Potential energy and kinetic energy can be converted one to the other but they are not the same thing.
