5.3 Oscillations Flashcards
1
Q
What is simple harmonic motion?
A
When acceleration of the oscillator is directly proportional to the displacement
2
Q
What are the 2 equation used to determine the displacement if simple harmonic oscillated?
A
x= Asin wt
x = Acos wt
3
Q
When do you use sin equation and when do you use cos equation?
A
-Sine = begins at equilibrium
-Cos = begins at amplitude
