Definition: Degrees per second (deg/s) is a unit of angular speed. It represents the rate of change of an angle in degrees over time, specifically the number of degrees rotated in one second.

History/origin: The degree as a unit of angle measurement dates back to ancient civilizations. The need to measure angular speed in engineering and physics led to the use of 'degrees per second' as a practical unit.

Current use: Degrees per second is used in various applications including robotics (measuring the speed of joint rotations), aviation (measuring the rate of turn of an aircraft), gaming (controlling the sensitivity of mouse or joystick movements), and navigation systems. It's a common unit for describing angular velocity in dynamic systems.
