2. Find the Relationship between F C and v Mass What were kept constant in this Experiment?  Radius  Mass

3. Find the Relationship between v and m stopper Mass What must be kept constant in this Experiment?  Radius  Hanging mass (weight)

4. Find the Relationship between v and r Mass What must be kept constant in this Experiment?  Mass of stopper  Hanging mass (weight)

5. Circular Motion Lab Results If the sum of the forces on an object is pointed toward a common center of rotation, perpendicular to its velocity, it will travel in a circle at a constant speed.
