> [!summary] Uniform circular motion describes an object rotating around a circle with constant linear speed. >[!info]+ Read Time **⏱ 1 min** # Definition Uniform circular motion is an object rotating at with constant [[Speed|linear speed.]] An object in uniform circular motion will also have constant [[Angular Speed|angular speed]]. The rotation around a circle is caused by the [[Centripetal Force|centripetal force]] and [[Centripetal Acceleration|centripetal acceleration]], which are always perpendicular to [[Velocity|linear velocity vector]]. ![[ucm_1.png|450]] [^1] > [!note] Explanation Example of uniform circular acceleration. Linear velocity is perpendicular to the centripetal force [^1]: Taken from https://tikz.net/dynamics_circle/ by Izaak Neutelings (October 2020)
