Problem 20

Two friends are having a conversation. Anna says a satellite in orbit is in freefall because the satellite keeps falling toward Earth. Tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/s2 . Who do you agree with and why?

Step-by-Step Solution:
Step 1 of 3

1 Chapter 1 I. Chemistry and Its Methods 1. Matter and the Changes it undergoes – A pure substance changes into another either natural or synthetic substance. 2. Scientific Method  Hypothesis – tentative explanation or prediction  Law – after hypothesis has been tested (numerous)  Theory – Well tested/unifying principle that explains a body of facts.  Data o Quantitative = numbers (ex. Temp, mass, etc) o Qualitative = observations (ex. color change) II. Classifying Matter 1. Matter – has Mass & Occupies Space 3 Phases 2 Solid ­ Fixed Shape & Volume Liquid – Shape Not Fixed; Volume is fixed Gas – Shape & Volume Not Fixed 2. Kinetic­molecular Theory of Matter o Solids – particles are packed closely together/ vibrate in position. o Liquids – particles arranged randomly but in contact/ slide past one another o Gases – particles are far apart/ in constant random motion. 3. Three Levels of Understanding Chemistry Macroscopic Submicroscopic Symbolic Matter Mixtures Pure Substances Heterogeneous Homogeneous Elements Compounds 3 Coarse
