What is Physics? Branch of science which describes the physical world Describes the world using math Uses mathematical models to predict certain phenomena

Topics Covered In This Course Linear Motion Two Dimensional Motion Newton’s Laws and Forces Momentum Work and Energy Rotational Motion Waves Sound Light Geometric Optics Electrostatics

The Metric System All answers must be in standard units, which correspond to metric units Seconds, meters, and kilograms are standard units.

Metric Prefixes

Significant Digits Significant digits are important in labs in this class, not on tests or homework All non-zero digits are significant Zeros are more complicated

Zeros As Significant Digits Zeros between two 504 has 3 sigdigs 40. 05 has 4 sigdigs other significant zeros are significant All final zeros after 45 has 2 sigdigs the decimal point 45. 0 has 3 are significant sigdigs Zeros used solely for 810 has 2 sigdigs spacing the decimal 810. 0 has 4 sigdigs point are not significant
