MC: effect of mass on frequency MC: total distance travelled MC: time for total distance travelled Ex: spring constant and frequency of oscillations Ex: maximum force and spring constant Vertical Springs Energy in Simple Harmonic Motion energy bar diagrams MC: doubling the amplitude MC: doubling the amplitude II MC: interpreting graphs Ex: Determine the frequency Ex: horizontal launching Ex: velocity in mid cycle Waves in elastic media Introduction to Mechanical Waves transverse and longitudinal waves period, wavelength, velocity Sound Waves in a gas: pressure peaks and valleys particle speed does not equal wave speed speed of wave depends on the medium speed of sound depends on material Speed of transverse waves on string depends on tension and linear mass density MC: Which properties are related to wave speed? MC: Can a wave accelerate? Ex: transverse waves on a string Ex: determining acceleration due to gravity waves transport momentum and energy: dominoes analogy Interference: the fundamental difference between waves and particles interference: the principle of linear superpostion constructive versus destructive interference making standing waves making standing water waves standing waves on a string Transverse Standing Waves MC: standing waves I MC: standing waves II Ex: a violin
