... Positions of Stable Equilibrium. An example is point x4 where U has a minimum. If we arrange Emec = 1 J then K = 0 at point x4. A particle with Emec = 1 J is stationary at x4. If we displace slightly the particle either to the right or to the left of x4 the force tends to bring it back to the equili ...

Chapter 2. Thermodynamics
... In the microscopic view of thermodynamics, entropy characterizes the state of disorder of a system. Consequently, entropy changes are closely related to heat, but are not at all associated with work. The work that raises a weight by a frictionless pulley does not affect the state of order or organiz ...
