1. Friction (Static and Kinetic)

2. Key Equations

3. Graphical view of Friction

4. Example: Dumping a file cabinet
What is the size of fs
At what angle of inclination
would the cabinet begins to slide?

5. Application of Newton’s Second Law (A more involved example)
In the above problem, determine the stopping distance of the car.

6. Physical Representation

7. Chapter 6: Motion in a Plane

8. Position and Velocity in 2-D
Displacement
Velocity
Average velocity
Instantaneous velocity

9. Components of Velocity in 2-D
Instantaneous velocity at any point on the curve is along the tangent drawn at that point
Average velocity points in the direction of the displacement vector

10. Components of velocity
