Its displacement from the mean position (x), velocity (v), and acceleration (a) at any instant are x = A sin ωt = A sin `((2π)/"T""t")` .........`(∴ ω = (2π)/"T")` v = `"dv"/"dt"` = ωA cos ωt = ωA cos `((2π)/"T""t")` a = − ω2A sin ωt = − ω2A sin `((2π)/"T""t")` as the initial phase x = 0. Using these expressions, the values of x, v, and a at the end of every quarter of a period, starting from t = 0, are tabulated below.
Using the values in the table we can plot graphs of displacement, velocity, and acceleration with time Graphs of displacement, velocity, and acceleration with time for a particle in SHM starting from the mean position Conclusions:
