Assumes rotational speed remains constant; varying speeds require more complex analysis.
-
Not intended for time-dependent or non-uniform angular velocity conditions.
Frequently Asked Questions
-
What does revolution per minute (r/min) measure?
-
Revolution per minute measures how many complete turns an object makes about an axis per minute.
-
How is radian per minute (rad/min) related to revolution per minute?
-
Radian per minute measures the angle swept in radians per minute, where one revolution per minute equals 2π radians per minute.
-
Why convert from r/min to rad/min?
-
Converting to rad/min allows expressing rotational speed in SI units, essential for scientific, control, and simulation applications.
Key Terminology
-
Revolution per minute (r/min)
-
A unit of rotational speed representing the number of complete turns an object makes per minute.
-
Radian per minute (rad/min)
-
An SI-derived unit expressing angular velocity as radians swept per minute.
-
Angular velocity
-
The rate at which an object's angular position changes with time, often measured in radian per second or per minute.
