  1. Particle Kinematics: Intro to Curvilinear Motion Current unit: Particle Kinematics Last two classes: Straight Line Motion Today: (a) Intro to Curvilinear Motion (b) Circular Motion (c) Projectile Motion

  2. Introduction to Curvilinear Motion Key Principle #1: Velocity is always tangent to the path. Knowing this… Can use path slope to get velocity angle. or, Can use velocity components to get path slope.

  3. Introduction to Curvilinear Motion Key Principle #2: Acceleration always acts toward the concave side of the curve.

  4. Intro to Curvilinear Motion Key Principle #3: an acts toward the center of curvature and may be calc’d from an = v2/r
