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 |
