In this section, we examine some examples of damped harmonic motion and see how to modify the equations of motion to describe this more general case. A guitar string stops oscillating a few seconds after being plucked.
Activity Overview. In this activity, students explore the properties of waveforms representing damped and driven simple harmonic motion. First, they identify the functional form of the damping in a simple harmonic oscillator.
Damped Harmonic Motion: Illustrating the position against time of our object moving in simple harmonic motion. We see that for small damping, the amplitude of our motion slowly decreases over time. The simplest and most commonly seen case occurs when the frictional force is proportional to an object’s velocity.
(iii) The mass oscillates in damped harmonic motion before coming to rest. On the axes of Fig. 2.3, sketch a graph of the damped harmonic oscillation of the mass, from an initial displacement of 25.0 mm. (a) (i) State one feature from each of Fig. 2.1 and 2.2 which shows that the mass performs harmonic motion when released.
2.C. Damped Harmonic Motion. This week you will continue to study a mass oscillating on a vertical spring but will use masses that are purposefully large so that they experience a non-negligible damping force due to air drag. Background.
Physics 1120: Simple Harmonic Motion Solutions 1. A 1.75−kg particle moves as function of time as follows: x = 4cos(1.33t+π/5) where distance is measured in metres and time in seconds. (a) What is the amplitude, frequency, angular frequency, and period of this motion?
DAMPED HARMONIC MOTION: MOTION GRAPHS. I. Displacement versus time. Consider a simple harmonic oscillator (e.g., a mass connected to an ideal spring) that experiences a retarding force that is always proportional to the speed of the oscillator. At t = 0 the oscillator is displaced.
