Angular acceleration has physical dimensions of angle per time squared, measured in SI units of radians per second squared (rad ⋅ s-2). In two dimensions, angular acceleration is a pseudoscalar whose sign is taken to be positive if the angular speed increases counterclockwise or decreases clockwise, and is taken to be negative if the angular ...
The SI unit of angular velocity is radians per second, [3] although degrees per second (°/s) is also common. The radian is a dimensionless quantity , thus the SI units of angular velocity are dimensionally equivalent to reciprocal seconds , s −1 , although rad/s is preferable to avoid confusion with rotation velocity in units of hertz (also ...
Disintegrations per minute (dpm) and disintegrations per second (dps) are measures of the activity of the source of radioactivity. The SI unit of radioactivity, the becquerel (Bq), is equivalent to one disintegration per second. This unit should not be confused with cps, which is the number of counts received by an instrument from the source.

Analogous to linear motion, the angular rotation rate (degrees per second) is obtained by integrating α over time: = and the angular rotation is the time integral of the rate: = The three principal moments of inertia I x , I y , and I z about the roll, pitch and yaw axes, are determined through the vehicle's center of mass .

The radian per second (symbol: rad⋅s −1 or rad/s) is the unit of angular velocity in the International System of Units (SI). The radian per second is also the SI unit of angular frequency (symbol ω, omega). The radian per second is defined as the angular frequency that results in the angular displacement increasing by one radian every ...
