5.3 Oscillations Flashcards
Angular frequency
Product 2(pi)f or (2pi)/T
Phase difference
The fraction of a complete cycle or oscillation between two oscillating points, expressed in degress or radians
Simple harmonic motion
a body will oscillate with shm if its acceleration is directly proportional to its displacement from a fixed point and always directed towards that fixed point
Vmax = ?
(omega) A
2 x pi x frequency x Amplitude
Amax
(omega)^2 A
4 x pi x pi x frequency x frequency x Amplitude
