Figure 7.22a shows the potentialenergy function for the force Fx = -kx. Sketch the potentialenergy function for the force Fx = +kx. For this force, is x = 0 a point of equilibrium? Is this equilibrium stable or unstable? Explain.
Unit 5: Entropy We are talking about the same entropy that you use in, say, the Gibbs free energy in chemistry courses That being said, get the word “disorder” out of your head Give a confusing idea of entropy “Discarding the archaic idea of "disorder" in regard to entropy is essential. It just doesn't make scientific sense in the 21st century and its apparent convenience often is flat-out misleading. As of November 2005, fifteen first-year college texts have deleted “entropy is disorder” although a few still retain references to energy “becoming disorderly”. (This latter description is meaningless, as I shall mention here, and discuss in detail in "Disorder — A Cracked Crutch For Supporting Entropy".) Most high sc
