What is the formula for restoring force in SHM?
Look for the relation between force and displacement.
Define amplitude.
Consider the height of a wave crest.
What is the restoring force equation in SHM?
Focus on the concepts of restoration towards equilibrium.
True or False: SHM energy is conserved.
Consider the oscillation of energy types.
A string fixed at both ends vibrates with frequency 150 Hz. If the speed of the wave on the string is 300 m/s, what is the wavelength?
Apply the wave speed formula that relates frequency and wavelength.
Calculate the observed frequency when a sound source moves away from an observer at 20 m/s, while the sound speed is 340 m/s.
Use the Doppler Effect formula to relate source and observer distances.
