3 If you displace a system that obeys Hooke s Law, It will follow simple harmonic motion. The system will oscillate. A graph of position versus time, will look like a sinusoidal function. Example: mass attached to a spring swinging pendulum (for small oscillations)
4 Important Definitions
5 For an object moving with simple harmonic motion (SHM) we can look at Newton s 2 nd Law. ΣF = m a F = -k x a= F/m = -k( x)/m The acceleration depends on the current amount of displacement. See quick quiz 13.2

15 Damped Oscillations Previously we looked at systems that would oscillate indefinitely. lack of friction smooth pivot points no external forces that impede motion For real mechanical systems, this is not the case. Friction will damp the motion. Other examples: pushing a kid on a swing, out of phase with the motion air resistance on a pendulum
16 Damped Oscillations Any mechanical system with some resistive force will not oscillate forever. The motion is damped. See figures and This is how the shock absorbers on your car work. They are slightly underdamped.
17 Waves Related to the energy of a vibrating object. All waves (sound waves, waves on a string, seismic waves, water waves, electromagnetic waves, ) have a vibrating object as their source. We can apply SHM to describe the waves. Let s first define a wave: The motion of a disturbance. Example: the surface of water after dropping a stone in the water. After the stone is dropped, we can observe the propagation of the disturbed water.
18 1) A source of disturbance. Waves need 2) A medium that can be disturbed. Electromagnetic waves don t need a medium, they are special. 3) Some physical connection through which the adjacent portions of the medium influence each other.
19 Types of waves Describe the waves based on the motion of the disturbance. Traveling wave wave in which the disturbance moves figure Standing wave wave where the disturbances do not travel across the medium. Result of superposition of traveling waves. Will use these in chapter 14.
20 Types of Waves Describe waves based on direction of disturbances. Transverse waves the medium is disturbed perpendicular to the direction of wave motion. example: waves on a guitar string. Longitudinal waves the medium is disturbed parallel to the direction of wave motion. example: sound waves See figure 13.23
21 Water waves are a combination of transverse and longitudinal waves.
22 Waves have alternating maxima and minima separated by nodes. At a node, there is no displacement (no disturbance). In transverse waves, the maxima and minima are crests and troughs. In a longitudinal wave, the maxima and minima are regions of high density and low density. See figure 13.25
23
24 Light and sound are two important waves to be studied. Both light and sound are waves. Biggest difference is that light (electromagnetic wave) does not need a medium to be disturbed. Light can travel through the vacuum of space. Sound longitudinal wave. Light transverse wave made up of two waves, varying electric field, and magnetic field perpendicular to each other. Compare frequencies of light and sound waves IF the wavelengths are the same. Example 13.9
25 Waves on a string Pluck a string perpendicularly to the direction of the string s orientation. Important quantities: Tension Mass per unit length. Higher tension quicker response to motion => higher frequency => higher speed Higher mass per unit length more inertia => vibrates slower => lower speed.
26 This is why different guitar strings sound differently. The strings have different mass per lengths and why you tune a guitar by adjusting the tension.
27 Interference of Waves When two traveling waves meet. They pass through each other without changing. When they overlap, they add up. This is a superposition principle. You just have to add up the individual displacements of each waves point by point. See figures on pages 470, 471
28
29 Reflection When a wave encounters a change in medium, the wave reflects, or bounce back. Examples: string tied to a pole light hitting a mirror ocean wave reaching a shore How the reflection occurs depends on the boundary conditions. See page 472. To complicate things we can have situations where some of the wave is reflected, while the rest of the wave is transmitted into a new medium.
