3.6.1.3 - Simple Harmonic Systems Flashcards
1
Q
When is kinetic energy max?
A
At equilibrium
2
Q
When is GPE max?
A
At the points of max amplitude
3
Q
Ep=
A
1/2 kx^2
4
Q
Ek=
A
1/2 k(A^2 - x^2)
5
Q
Et =
A
1/2 kA
6
Q
For a mass spring system what is a = to?
A
-kx/ m
7
Q
What does damping cause?
A
Damping forces cause the amplitude of oscillations to decrease with time.
8
Q
What happens to the time period as the amplitude decreases due to damping?
A
Time period stays constant.
9
Q
What is heavy damping?
A
The amplitude of oscillation struggles to return to equilibrium. No oscillating motion occurs.
10
Q
What is critical damping?
A
The amplitude of the oscillation decreases to zero in the shortest possible time and does not overshoot the equilibrium position.
11
Q
What does lightly damped mean?
A
Amplitude decreases by the same fraction each time.
