Document Summary
Pick up the 2 sided handout at the front desk . : sample formula sheet & quiz/exam instructions. Assignments for friday: read ahead meriam & kraige: 2. 6 polar/cylindrical coord, practice prob #03 2. Class representatives name underlined on sign-in sheet. Practice quiz #1 friday = covers thru today cartesian/path kinematic"s: topics for the day. Curvilinear kinematics: coordinate expressions for: pos <=> vel <=> accel. Path (normal-tangential: conversion between coordinate systems. Vectors are your friend: example problem(s) Curvilinear motion: cartesian coordinates & vector derivatives: position r(t) = x(t)i + y(t)j + z(t)k. = x(t), y(t), z(t: velocity v(t) = r (t) = x i + y j + z k. = v xi + v y j + vz k. = v x (t), vy (t), vz (t) X: acceleration a(t) = r (t) = x i + y j + z x i + v y j + v k = v z k.
