Definition

Radians are a unit of measurement for angles, where one radian is equal to the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle. In other words, radians measure how much of a full circle an angle covers.

This definition is part of Fiveable's AP Physics 1 review, which also has guided practice questions.
