  1. Section 2: Centripetal Force

  2. Warm Up: • Define Force: 2) Define Acceleration: The acceleration is always in the direction………

  3. Centripetal Force: Force required to keep an object in circular motion.

  4. Centripetal Force Discovery: • What direction is the centripetal force in? • What happens to the force as the angular speed increases? • What happens to the force as the Radius increase? • What happens to the force if the tangential velocity stays the same and radius decreases?

  5. Centripetal Force Properties: 1) Centripetal Force Direction: 2) If the Tangential Speed increases the centripetal force will: 3) If the Angular Speed increases the centripetal force will: 4) If the radius decreases and the velocity stays constant the centripetal force will: 5) Which will have the greatest centripetal force

  6. Which has the greatest centripetal force Two candies are placed on a spinning table, which one will have the greatest centripetal force.

  7. Demo: • Water Bucket

  8. Demo: Flame

  9. Demo: Penny and Hanger Wet towel

  10. Technology Applications Racetrack Steel wire in tires and treads: everything but chains are good on ice Engine blade and design

  11. Centripetal Force Derivation Newton 2nd Law: F = mxa For Centripetal Force “Fc” Fc=mxac where ac – centripetal Acceleration ac=Vt2/r

  12. Sample Problem 1: A 8kg weight is spun at 3m/s at a radius of 1 meter before being thrown. Find the following. Centripetal Acceleration b) Centripetal Force Centripetal Force Equation

  13. Sample Problem 2: Find the normal force at the following locations if the cart has a mass of 10kg:
