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
4
Q
How do you work out the velocity in the equation.
A
Draw a gradient on the graph
5
Q
When does maximum velocity occur?
A
-At equilibrium position
6
Q
how do you work out phase differnece?
A
Δt/t *2 pi
7
Q
Define damping
A
Damping is the process by which the amplitude of the oscillations decreases over time. This is due to energy loss to resistive forces such as drag or friction.
