Chapter 2 – kinematics of particles Tuesday, September 1, 2015: Lecture 4 Today’s Objective: Curvilinear motion Normal and Tangential Components Coordinate Systems Plane Curvilinear Motion: Velocity Note the direction of acceleration. It’s not predictable! Acceleration Note: The curve isn’t the path of the particle, it’s a plot of the velocity! Rectangular Vector Coordinates Normal and Tangential Coordinates • Used when Motion is along a curve • n-t coordinates are most effective
