Unformatted text preview: Introduction Physics provides quantitative explanations to the basic phenomena in our universe based on experimental observations and mathematical analyses . Physics approach: observations building an idealized model with assumptions and simplifications establishing theories in mathematical equations validating theo ries by experiments Units and Standards: An equation must be dimensionally consistent, and watch for unit consistency in numerical computations. We work with SI system in this course. In mechanics, there are four fundamental units: Time sec, Length m, Mass Kg, and Temperature K . Significant figures: Keep all digits on your calculator in the intermediate computations, and present your final answers with 3 sigfigs . Vectors: Brief review Definition of vector: A vector quantity has a magnitude and a direction. The length of the line segment represents the magnitude of the vector and in 2D its direction is defined by an angle measured from some...
