PHSX 114 First Midterm Review Sheet Chapters 1 through 2 -- Spring 2009 Terminology: y displacement y velocity y acceleration y vector y scalar Principles: y constant acceleration equations follow from basic definitions y objects fall with the same acceleration regardless of mass Skills: y know proper SI units for quantities, be able to convert from one set of units to another y describe motion in terms of displacement, velocity, acceleration y represent motion on graphs and interpret graphs (x vs. t, v vs. t) Equations: Circumference of circle: 2 π r Area of circle :
