HAWKINS REVIEW #1: INTRO TO CH 1 & 2 CHAPTER 1 – INTRO TO PHYSICS ● Physics is the study of natural phenomena, including LOTS of measurements and equations. It’s math with rules. UNITS IN PHYSICS ● In science, we measure physical quantities. Measurements have __________. We also have lots of _______________. - Units have to be _________________ with one another for equations to “work”. For example: F = m a ( Force = Mass * Acceleration ) [ ] = [ ] [
