Chapter 5 Work and Friction
... Work and Friction We have been looking at systems without friction—that bounce and swing without losing energy. The energy may change from kinetic (motion) to potential (gravity and springs) and back again, but it stays the same—it’s conserved. Friction causes things to slow down, and the energy is ...

... Indeed, the same result would have been obtained by Newton’s law (balance of forces) applied to the three masses. For the unforced (u = 0) equilibrium configurations, we set q̇ = q̈ = 0 in (2) and obtain an infinity of equilibria q 0 , all with equal q1 = q2 = q3 at a common arbitrary value. The two ...
