Solution for On-Line Homework 25 Periodic Motion II Solution to On-Line Homework Problem 25.1() Problem: Explain what each term in the following equation for the position of a simple harmonic oscillator represents: x ( t ) = A sin( ωt + φ 0 ) Select One of the Following: (a) A is the displacement, ω is the angular fre- quency, t is the time at which the position is be- ing evaluated, and φ 0 is the initial phase at time t = 0 . (b-Answer) A is the maximum displacement, ω is the angular frequency, t is the time at which the position is being evaluated, and φ 0 is the initial phase at time t = 0 . (c) A is the displacement, ω is the linear frequency, t is the time at which the position is being eval- uated, and φ 0 is the initial phase at time t = 0 . (d) A is the maximum displacement, ω is the linear frequency, t is the time at which the position is being evaluated, and φ 0 is the initial phase at time t = 0 . (e) A is the maximum displacement, ω is the angu-
