Document Summary

Phya11 lec02 september 14 2011 calculus: assume someone tells you the positon "x" of an object at any time "t" is : s(t) = s(subsc 1) + v(subsc is) t + 1/2a(subsc s) t^2 kinematics: Many kinematic equations all just rearragements of two basic equations v(subsc fs) = v (subsc is) + a(subsc s) delta t s(subsc f) s (subsc is) delta t + a(subsc s) (delta t^2) [v(subsc fs)]^2 = [v(subsc is)]^2 +2a(subsc s) delta s motion in 2d and 3d important concepts: Magnitude vs direction directions => coordinte systems separate directions => indices. Learn these vectors: have a magnitude and a direction can be multipliedin two different ways have a specific way they are added together co-ordinate systems if you have a 2d problem, you need two coordinates (usually x and y)
