January 3, 2012 Physics 114A - Lecture 1 3/21 January 3, 2011 Physics and the Laws of Nature Physics: the study of the fundamental laws of  nature.  These laws can be expressed as mathematical  equations .   (e.g., F = m a)  Most physical quantities have  units , which must  match on both sides of an equation.  Much  complexity  can arise from even relatively  simple physical laws.

January 3, 2012 Physics 114A - Lecture 1 4/21 Units With a few exceptions, all physical quantities have units.  Examples: Mass - kilograms (kg) Speed - meters per second (m/s) Pressure - pascals (P) Energy - joules (J) Electric Potential - volts (V)     Rather surprisingly, the units of almost  all physical quantities can be  expressed as combinations of  only  the units for  mass length , and  time , i.e., kilograms, meters, and seconds.  A few physical quantities  (e.g., index of refraction) are pure numbers that have no associated units.
