  1. Friction Static Kinetic Incline/Horizontal Plane with friction Drag Forces Terminal Velocity Uniform Circular Motion Banked and Flat Turns Cresting Hills Loop the Loops Conical Pendulums Ferris Wheels Aircraft Turns Chapter 5 - Force and Motion II

  2. Friction

  3. Coefficients of Friction

  4. To push or pull a sled? Or

  5. Measuring coefficients of friction

  6. Two boxes and a pulley

  7. Incline plane (no friction) • m2 = 7 kg • Which way do blocks move? • What is acceleration? • What is tension in cord?

  8. Incline plane (friction) • What range of masses keep the blocks at rest? • If m2 = 10 kg, determine the system acceleration

  9. Uniform Circular Motion

  10. Banked Roads No friction required:

  11. Conical Pendulum

  12. Motion in a vertical circle with gravity • m = .150 kg • r = 1.10 m • Find minimum speed to continue moving in a circle • If speed is twice this minimum, find tension in cord at top and bottom.

  13. Demo

  14. Non-uniform circular motion

  15. Velocity Dependent ForcesTerminal Velocity
