| Sonata No. 1 Op.78 in G | |
| violin and piano (1879) |
| Motion that repeats at regular intervals of time |
| Oscillation | ||
| One complete round trip of the motion | ||
| Period | ||
| The time required for one complete oscillation | ||
| Frequency | ||
| The number of oscillations per second | ||
| Equilibrium Position | ||
| The rest (or neutral) position | ||
| Displacement | ||
| The distance from the equilibrium position | ||
| Amplitude | ||
| The maximum displace-ment (absolute value) | ||
| Period - Time (Usually seconds) | ||
| Frequency - Oscillations (or cycles) per second | ||
| One cycle per second is called one Hertz (Hz) | ||
| Displacement - Distance | ||
| May be cm, m, ft, degrees, etc. | ||
| Amplitude - Distance | ||
| May be cm, m, ft, degrees, etc. | ||
| f = 1/T | |
| or | |
| T = 1/f |
| The frequency is independent of the amplitude | |
| The greater the inertia factor, the less the frequency | |
| The greater the stiffness factor, the greater the frequency |
| Relation between frequency and weight: |
| Relation between frequency and spring constant: |
| The frequency is independent of the amplitude | |
| The greater the inertia factor, the less the frequency | |
| The greater the stiffness factor, the greater the frequency |
| Occurs whenever an oscillating system is driven at its natural frequency |
| Under resonant conditions, a system oscillates at its maximum amplitude |
| In Phase (0 degrees) | |
| Out of Phase (180 degrees) | |
| Measured in degrees |
