  1. Physics IClass 12 Uniform Circular Motion

  2. Newton’s Second Law -Yet Another Review!

  3. Uniform Circular Motion

  4. When an object travels in a circle, its velocity is constantly changing (in direction at least). That means the object has a non-zero acceleration even if it moves at constant speed. Acceleration in Circular Motion

  5. Important Facts AboutVelocity and Acceleration Vectors

  6. What is the Direction of Acceleration?

  7. “Centripetal Force”“Centrifugal Force”

  8. Example:A Rock on a String Twirl a 1 kg rock attached to a string in a 1 m radius vertical circle. The speed is 4 m/sec. What forces act on the rock and what are the directions of those forces?

  9. Using Newton’s Second Law to Solve Problems - Review

  10. Case A:Rock at the Top of the Circle

  11. Case B:Rock at the Bottom of the Circle

  12. Normal Force - A ConceptWe Will Use in Today’s Activity

  13. Class #12Take-Away Concepts
