The first law of thermodynamics was expressed in two ways by Clausius. One way referred to cyclic processes and the inputs and outputs of the system, but did not refer to increments in the internal state of the system. The other way referred to any incremental change in the internal state of the system, and did not expect the process to be cyclic. A cyclic process is one which can be repeated indefinitely often and still eventually leave the system in its original state.
In each repetition of a cyclic process, the work done by the system is proportional to the heat consumed by the system. In a cyclic process in which the system does work on its surroundings, it is necessary that some heat be taken in by the system and some be put out, and the difference is the heat consumed by the system in the process. The constant of proportionality is universal and independent of the system and was measured by Joule in 1845 and 1847.
In any incremental process, the change in the internal energy is considered due to a combination of heat added to the system and work done by the system. Taking dU as an infinitesimal (differential) change in internal energy, one writes........copied from wikipedia.

I dont have the math background to go into the details of this but as far as I can determine, if we substituted "motion" for "work", (in the sense that to move entails a certain amount of work and vice versa), then we could conclude....motion=heat.
An oversimplification,I know but essentially true, No? If this is incorrect or misleading Id appreciate it if youo math and physics guys would please correct and enlighten me. Ill explain why later.
