Summary for Physics 131 Lecture 1, Sept. 19, 2007 1. Use Kilogram-meter-second system. 2. Need a coordinate system to define kinematical variables. 1. Position in meters is defined with respect to the chosen coordinate system. 2. Velocity is the rate of change of position in m/s, and is the slope of the position versus time graph: -x 0 +x dt dx t x lim V t x t t x x v 0 t INST 1 2 1 2 AV δ δ = δ δ - - = δ x t V is slope
