... Equation 5.1 shows that the kinetic energy increases as the speed of an object increases. For example, a car moving at 55 miles per hour (mph) has greater kinetic energy than it does at 40 mph. For a given speed the kinetic energy increases with increasing mass. Thus, a large sport-utility vehicle t ...

the concept of exergy and energy quality
... As indicated in Figure 4, Thermo-mechanical Exergy can be decomposed into a pressure based part and a temperature based part. This decomposition has no real fundamental significance, and is only done as a matter of convenience as will be described below. In fact, the decomposition is not even unique ...
