Oscillations and Waves (Physics)
✅Any motion that repeats itself over the same pathway.
Periodic Motion-
Simple Harmonic Motion (SHM)-✅Periodic motion that occurs because of
a restoring force (always trying to get back to the equilibrium point). Ex:
swinging mass/pendulum or mass on a spring.
Vibration-✅back and forth motion
Frequency-✅cycles/time (Hz)
Period-✅1/f (inverse of frequency)
Pulse-✅a single disturbance
Wave-✅a vibration (series of pulses) that move out through space
Sine Wave-✅a pictorial representation of waves
Crest-✅top of wave (highest point)
Trough-✅lowest point of wave
Equilibrium-✅resting position/middle position
Amplitude-✅maximum displacement from equilibrium. measures strength
and energy of a wave.
✅
Wavelength- distance from any 2 identical successive parts of a wave.
Ex: crest to crest, trough to trough, etc.
Medium-✅what a wave passes through. Ex: air, water, slinky, etc.
Mechanical Wave-✅needs a medium to travel. Ex: sound waves
