RPM to Angular Frequency Formula:
| From: | To: |
Angular frequency (ω) is a scalar measure of rotation rate, representing how fast an object rotates or revolves relative to another point. It is measured in radians per second and is related to rotational speed.
The calculator uses the RPM to angular frequency conversion formula:
Where:
Explanation: The formula converts rotational speed in revolutions per minute to angular frequency in radians per second by accounting for the unit conversions between revolutions and radians, and minutes and seconds.
Details: Angular frequency is crucial in physics and engineering for analyzing rotational motion, designing mechanical systems, calculating centripetal forces, and understanding oscillatory systems like springs and pendulums.
Tips: Enter RPM (revolutions per minute) as a positive number. The calculator will automatically compute the corresponding angular frequency in radians per second.
Q1: What is the difference between angular frequency and regular frequency?
A: Angular frequency (ω) is measured in radians per second, while regular frequency (f) is measured in hertz (revolutions per second). They are related by ω = 2πf.
Q2: Can angular frequency be negative?
A: Angular frequency is typically positive as it represents magnitude. However, angular velocity can be negative to indicate direction of rotation.
Q3: What are typical angular frequency values?
A: Common values range from very small (0.001 rad/s for slow rotations) to very large (1000+ rad/s for high-speed machinery).
Q4: How is angular frequency used in real applications?
A: Used in motor design, gear systems, vibration analysis, electrical engineering (AC circuits), and celestial mechanics.
Q5: What's the relationship between angular frequency and linear velocity?
A: Linear velocity v = ω × r, where r is the radius from the axis of rotation.
