The First Law of Thermodynamics The first law of thermodynamics is also known as the "Law of Conservation of Energy".    First Law:  Energy can be converted from one form to another but can be neither  created nor destroyed. Energy is classified into one of two forms:     Potential Energy:  Depends on object's position or composition     Kinetic Energy:  Depends on object's motion, that is, E kinetic  =  ½mv 2 , where m and v are  the object's mass and velocity, respectively. Consider the example of a marble rolling in a bowl. At any instant in time, t, the marble has a potential energy given by E potential  = mgh(t) Here g is the acceleration constant due to gravity. The kinetic energy, at any instant in  time t is given by E kinetic  =  ½  mv 2 (t) When the marble is at the maximum height, h max , its potential energy will be at a  maximum, and its kinetic energy at a minimum (
