Circular Motion
Alignment with KY Program of Studies: Multi-dimensional Motion
What you should know when all is said and done
By the time you finish all labs, worksheets and related activities, you should be able to:
1. Graph and state the relationships between Force and mass, Force and radius, and Force and period for an object undergoing uniform circular motion.
2. State the mathematical model which describes the relationship between Force, mass, radius and period.
3. State the mathematical model for centripetal force. Use the mathematical model to solve for the missing variable, given the other two.
4. Distinguish between centripetal and centrifugal force.
5. Construct force diagrams which display the force acting on an object undergoing uniform circular motion.
Core Content:
Laws of motion. Objects change their motion only when a net force is applied. Laws of motion are used to predict and/or calculate the effects of forces on the motion of objects.

Lost Worksheets-- You can get some of them here
Fun to Try
Bend a wire coat hanger. Place a quarter on the hook of the coat hanger. Swing the quarter on the hanger over you head. The hardest part is getting the quarter to sit on the hanger hook, you may need to file the hook.
