Simple Harmonic Motion (SHM): The most general form of the equation that describes any object undergoing SHM is given by: • A is the amplitude, . y(t) = A sin (2+)+ B T is the period of oscillation, • is a constant phase factor, and . B is the equilibrium value of y(t), if it is not zero. We will normally let B = 0. 2) The constant phase factor tells about the initial conditions of the oscillating system, or the value of displacement y(t) at /-0. For B-0, 1-2, and 7-5, use the general expression above to sketch the following plots, all on the same graph. Your time axis should go from Os to = 10s, a) Make a position vs. time plot for a spring mass system where we call 1-0 the lowest position of the mass, once it's released after being pulled down. What value of o does this initial condition represent? b) Make another plot where at 1-0 the mass is moving down through its equilibrium position. What value of does this initial condition represent? c) Make two more plots for the cases of i) =0, and ii) =л/2. Which positions of the spring-mass at /= 0 do these values of represent?
