Page Uniform Circular MotionUniform Circular MotionNew TopicQuestion: A car drives around a circular track at a constant speed (say 30 mph). Is the velocityof the car constant?The speed is constant, this is true.However, thevelocity, which involves bothmagnitudeanddirection, is notconstant,since thedirectionis continually changing.Since velocity is not constant, the car is accelerating.
