Simple Harmonic Motion (SHM)  Review For an object to undergo SHM, there must be 1) An Equilibrium position: the position at which the net force acting on the object is zero 2) A linear Restoring Force : force acting on the object is always pointing towards equilibrium and has a magnitude which is proportional to the distance from equilibrium → F = -k x
SHM Review (cont’d) SHM constructs Amplitude (A) : maximum distance of object from equilibrium Period (T) : amount of time needed for object to complete one full cycle Frequency (f) : number of cycles per unit time Equilibrium position (y 0 ) : Position where the force on the object is zero Displacement (y) : position of the object with respect to equilibrium Fixed phase constant (φ) : Constant angle which allows us to specify initial position and initial velocity of object
