Radians
Radian Measure is used so that we can easily calculate an arc length, d (m), given an angle, š (Rad) and the radius, r (m).
d = rš
This in turn allows us to relate velocity, v (ms-1) to angular velocity ⍵ (rads-1), in the same way.v = r⍵,
also ⍵ = 2š f
This also allows us to relate acceleration, a (ms-2), to angular acceleration, Ī± (rads-2), in the same way.a = rĪ±
The rotational kinematics work just like the translational kinematic equations when there is a constant acceleration.
