... 1 J = 1 kg∙m /s 4. What is the SI unit for work? 5. Express your answer to #3 in terms of fundamental SI units (meters, kilograms, & seconds). "Work" has the same units as energy. In fact, sometimes work is called "useful energy", because the energy is actually doing something, in making something m ...

... The First Law of Thermodynamics: It generalizes the usual statement of conservation of mechanical energy encountered in Newtonian mechanics by also considering heat. It can be stated as follows: The change in internal energy U of a system equals to the heat Q added to it plus the work W done on the ...

... An inertial reference frame is one in which Newton’s first law is valid.This excludes rotating and accelerating frames. An example is a cup resting on the dashboard of a car. It will stay at rest as long as the car’s velocity remained constant. If the car is accelerating, the cup may begin to move t ...
