Uniform Circular Motion Lab Introduction Uniform circular motion is defined as the motion of an object travelling at a constant (uniform) speed on a circular path. There are several terms that can be applied to the study of uniform circular motion. A cycle can be defined as one complete motion around the circle. The period ( T ) of the motion can be defined as the time required to complete one complete cycle of the motion. Since this is a unit of time, the standard unit of time would be the second. The frequency ( f ) of motion can be defined as the number of complete cycles per second. The unit used to measure frequency is the hertz (Hz), named after the scientist Heinrich Hertz (1857- 94). One hertz is one cycle per second. The period of motion and the frequency of motion are inverses of each other. = = = frequency cyclestime f 1T = = = Period timecycles T 1f To determine the speed of any object moving in uniform circular motion, we can use: = v 2πrT = or v 2πrf At any time in uniform circular motion, the direction of the velocity is tangent to the circle. Another way of saying this is that the velocity vector is perpendicular to the radius. In uniform
