PHYS 221 Lecture Notes - Lecture 14: Circular Motion, Free Body Diagram, Kinetic Energy
Document Summary
Uniform circular motion motion of constant v at constant speed a mass in a circle r r. 2 magnitude of the velocity vector the direction of constant but changes constantly is u acceleration has constant magnitude but varying direction acceleration always points to the center of circle the acceleration and velocity are perpendicular always. Steps for solving uniform circular motion free body diagram. Conservative forces depends only on on path not final positions taken of initial the work done by that force conditions and initial and and final between the the mass. A pe can be defined non conservative force work done by that on the path taken between the initial and final positions of for conservative forces the mass force depends. A pe cannot be defined for non conservative forces the most. Wnet common non conservative force is friction wot wn. Wnc work done by non conservative forces work energy principle still holds i.
