Meaning
Angular frequency is the rate of change of angular displacement, often used in oscillatory systems.
About Angular Frequency
- Angular frequency is given by the symbol 'ω'
- Measured in radians per second (rad/s).
- Relates to the frequency of oscillation (f) by the formula ω = 2πf.
- Indicates how quickly an object moves through its circular path.
Formula
ω = 2πf
Where:
ω is the angular frequency.
f is the frequency of oscillations.
Examples
- The angular frequency of a pendulum can be calculated from its period.
- In alternating current (AC), angular frequency relates to the electrical frequency.
