Experiment11Centripetal ForceUniform Circular MotionThe purpose of this experiment was to determine the Centripital Force of a random weightWhen a body moves in a circle with constant speed the body is, nevertheless, accelerating. Acceleration is associated with the change in velocity with respect to a change in time. Since velocity is a vector, this special case of acceleration occurs because them is a continuing changein direction even though the magnitude of velocity is unchanging. This particular acceleration is called centripetal or “center seeking” acceleration. The directionof the acceleration vector points toward the center of the circle. The relation gives the magnitude ofthe acceleration:Eq(l)rva2cWhere acis the centripetal acceleration, vis the speed of the object, and ris the size of the radius of orbit about the central point.Whenever acceleration occurs, there must be an unbalanced force acting on the mass. By Newton's second law, F = ma
