PHSX 114 Fifth Midterm Review Sheet Chapters 9 through 11 -- Spring 2009 Terminology: y stable/unstable equilibrium y stress/strain y three common phases of matter y density y mole y pressure y oscillator y simple harmonic motion y linear restoring force y period y frequency/angular frequency y amplitude y simple pendulum y power y intensity y mechanical energy y transverse/longitudinal wave y wavelength y wave velocity y energy/intensity of wave y constructive/destructive interference y standing wave/resonance Principles: y Necessary conditions for an object in equilibrium: (1) sum of all forces must be zero, and (2) sum of all torques must be zero y Pressure at a depth h in liquid y Pascal principle y Archimedes’ principle y Equation of continuity y Bernoulli’s principle y Oscillatory motion occurs when you have an equilibrium position and a restoring force F=-kx . y The position x ( t ) of an object moving under a linear restoring force is described by a cosine function. y In simple harmonic motion, the frequency is independent of the amplitude, but the total mechanical energy depends upon the square of the amplitude.
