SUMMARY
The valid equation that requires angular measure to be expressed in radians is D: ω = Vt/r. This relationship defines angular velocity (ω) as the ratio of tangential velocity (Vt) to the radius (r) of the circular path. The discussion clarifies that Vt represents the tangential velocity of an object in circular motion, emphasizing the necessity of using radians for accurate calculations in rotational dynamics.
