... on the object (slope of U(x) = 0) it must either possess only potential energy and be at rest or, it also possesses kinetic energy and must be moving at a constant velocity. x4 is a position of unstable equilibrium. If the object is displaced ever so slightly from this position, the internal forces ...

... 6. Grab the block and lift it up the ramp. Then, select the play button, and observe the work and energy bar graphs as the block slides. The work shown is the work done by friction on the block. A more realistic picture of the block on a hill includes friction resisting the motion of the block. On a ...

Chapter 6: Entropy and the Laws of Thermodynamics
... As mentioned above, an increase in entropy is associated with an increase in randomness in the system. Thermal energy consists of the random motion of the molecules of which matter is composed. Recall that the random motion of molecules in solids is less vigorous than in liquids; the motion of molec ...
