  1. Aim: An Introduction to Physics

  2. Units This Year • Math Review • Kinematics • Energy • Electricity • Magnetism • Waves • Light • Modern

  3. Estimating nearest order of magnitude Human Lifespan 70 years (round to nearest base 10) 100 years 102 years Width of your fingernail 1 cm (no need to round) 10-2 m

  4. Height of a 12 story building (each story is about 10 meters) 120 meters 100 meters 102 meters

  5. Units • International System of Units (SI) • Fundamental SI units:

  6. Derived Units

  7. Common SI Comparisons Head of a pin = 2 mm Width of pinky = 1 cm Height of doorknob, distance between outstretched arms = 1 meter Height of 1 story = 10 m

  8. 1 liter of water = 1 kg Small person = 50 kg Football player = 100 kg Duration of a heartbeat at rest = 1 second

  9. Current flowing into a computer = 1 amp Maximum current to household device = 10 amps Water freezes at 273 Kelvin, boils at 373 Kelvin Room temperature is about 300 Kelvin 12 grams of Carbon-12, or the number of carbon atoms in the ‘lead’ of a pencil = 1 mol
