SHM Flashcards
1
Q
A body has SHM if
A
The magnitude of acceleration is proportional to displacement from a fixed point/eqbm
Direction of acceleration is always in the opposite direction to the displacement form the fixed point/eqbm
2
Q
Free Vibration
A
There are no dissipative forces (friction) and no periodic driving forces acting on the system
No net energy transfer so amplitude is same
3
Q
Damping
A
An expression of proportion of energy removed per oscillation
4
Q
Forced Vibrations
A
Occur when a periodic driving force is applied to the driven system
5
Q
Resonance
A
When the frequency of the driving oscillation is equal to the natural frequency of the driven system
