AP Q1 Class 2 - Motion Graphs - 2026-27

Class Start Routine:
- Cell phones must be placed away in the designated holder.
- Notebooks should be out and open for taking notes.
- iPads are to be out but remains closed unless otherwise directed.
- Calculators must be accessible for calculations.
- Students should begin working on the warmup question immediately.
Homework Submission:
- Homework is typically due by the start of class.
- The time listed in Canvas (such as $8\text{ a.m.}$ ) is considered a placeholder. If an assignment is submitted by the actual start of class, it is recorded as on time, even if Canvas flags it as late.
- Any exceptions to this rule where a specific assignment is due at a different time will be announced explicitly.
Course Materials and Accounts:
- Required items include the Syllabus, Honesty Statement, and Intro Survey.
- Students must maintain an AP Classroom Account.
- Information regarding AI usage and the provision of Equation sheets is central to class operations.

The Concept of Relative Motion:
- Motion is described as "relative" because all descriptions of motion depend entirely on the perspective or "reference frame" of the observer.
Defining a Reference Frame:
- A reference frame is defined for each physics problem to ensure a consistent perspective throughout the analysis.
- Key Elements:
  1. The specific location of the origin ( $0,0$ ).
  2. The designation of positive ( $+$ ) and negative ( $-$ ) directions for each axis.

Time ( $t$ ):
- Definition: When a specific event occurs.
- Standard Units: seconds
