9/27 Friction Introduction
- Text Chapter 4 section 9 friction
- HW 10/4 Elevator due Wednesday 10/2
- Friction worksheet up front

Friction
- Always acts parallel to the surface of contact
- Comes in two flavors static and kinetic
- Static no relative motion of surfaces
- Kinetic relative motion of surfaces (sliding)

Friction Worksheet
- Goals
- Conceptualize the difference between Static and
Kinetic friction - Discover what each type depends on (tricky as the
equations for them look identical) - Typo
- On page 2- The box moves at constant speed
throughout the page is not true. The first and
last FBDs are at constant speed.
