General Physics II
Test 1
| Question | Answer |
|---|---|
| Resonance is | when driving frequency is equal to the natural frequency of the oscillator. |
| Oscillations:(y)t= | A cos(wt+Oo) |
| Amplitude | m |
| omega(w)= | rad/s |
| Phase= | rad |
| Phase Shift= | rad |
| omega(w)= | squrt(k/m) or 2(pi)f |
| frequency(f)= | 1/T |
| T= | 2(pi)sqrt(m/k) |
| K= | N/m |
| Vmax= | omega(w)*A |
| amax= | omega(w)^2*A |
| Kmax= | (1/2)*k*A^2 |
| Pendulum: omega(w)= | squrt(g/l) |
| pendulum: T= | 2(pi)squrt(L/g) |
| k= | m*omega^2 |
| damped oscillations: y(t)= | Ae^(-t/T) |
| Pendulum: F= | 1/(2pi)*squrt(g/L) |
| Pendulum: T= | 2(pi)*squrt(L/g) |
| Waves: Vs= | squrt(Ts/(mass/L)) |
| Sound: B= | 10log(I/Io) |
| Standing Wave: f= | m(V/2*L) |
| sound: wavelength()= | 2L/m |
