Definitions: SHM Flashcards
1
Q
What is the necessary condition for SHM?
A
The acceleration must be directly proportional to displacement from the equilibrium position, but in the opposite direction.
2
Q
What is resonance and when does it occur?
A
Where the amplitude is large due to the driving force matching the natural frequency.
3
Q
Define Damping.
A
The effect that reduces the amplitude of oscillations.
4
Q
What is critical damping?
A
Where a system reaches rest at equilibrium as fast as possible with no oscillations.
5
Q
What is over-damping?
A
Where a system does not oscillate but reaches equilibrium slowly.
6
Q
What is under-damping?
A
Where a system oscillates under reducing amplitude before reaching equilibrium.
