1.
Critical damping is when the system
Oscillates many times
Returns to equilibrium fastest without oscillating
Never reaches equilibrium
Has infinite amplitude
2.
Increasing damping on a resonating system makes the peak
Lower and broader
Taller and narrower
Unchanged
Shifted to higher frequency
3.
A lightly damped oscillation falls by 20% in amplitude each cycle. After 2 cycles from 10 cm it is
8.0 cm
6.0 cm
4.0 cm
6.4 cm
4.
A car's shock absorbers are designed to give approximately
Light damping
No damping
Critical damping
Negative damping
5.
For a damped oscillation, energy is converted mainly into
Sound only
Thermal energy
Light
Gravitational potential energy
6.
An oscillator's amplitude drops to 0.9 of its value each cycle. Energy per cycle is multiplied by
0.81
0.90
0.45
0.99
