PHYSICS LAB EXPERIMENT : Simple Harmonic Motion
Document Content and Description Below
I. OBJECTIVE To study the behaviour of oscillations (Simple Harmonic Motion) in situation where there is resistive force of fluid investigated by study of exponential amplitude decay in the fluid as ... compared to relatively undamped environment of air. II. HYPOTHESIS During Simple Harmonic Motion (SHM) in damped fluid environment amplitude of oscillation decreases exponentially. And the rate of amplitude decay depends on viscosity of fluid medium. III. THEORY Simple Harmonic Motion (SHM), is a type of motion in which there is an restoring force which is always directed towards a unique point. In ideal conditions force equations on a object undergoing SHM is given by Hooke’s law, F = -kx Where, x is displacement from 0 stretch of spring and, k is the spring constant of the spring. Upon solving above equation, general form of the displacement, for SHM can be given as, x = Acos(wt+Φ) where, A is amplitude, w is angular frequency and, Φ is phase of the oscillation. [Show More]
