PHYS 1110 Study Guide - Midterm Guide: Pythagorean Theorem, Circular Motion, Coordinate System
Document Summary
Unit conversion, algebra, trigonometry (sin, cos, tan, pythagorean theorem) Graphing: x vs. t, v vs. t, a vs. t v a dx dt dv dt x t v t lim t. = slope of a graph of x vs. t. = slope of graph of v vs. t. Average vs. instantaneous value of velocity, acceleration. Constant acceleration (a = const) in 1d: (a) v (b) (c) x. 2 v (d) v v o x o a t v t o. Addition of vectors: graphically (tip-to-tail) analytically (with components) 0 r t a v t lim t. Direction of a = direction of v v. Circular motion with constant speed v, a a. 2v r a is toward the center (centripetal) Force and motion problems: free-body diagram, coordinate system with +direction of axis = direction of acceleration. Review concept tests, mp (masteringphysics) problems, tutorial hw. (read question and try to remember reasoning that gets to the answer)
