  1. Centrifugation A centrifuge is a useful device for chemical separation and a good example of circular motion. The purpose of a centrifuge is to provide an effective gravity much higher than normal See example 5-10

  2. Newton’s Law of Universal Gravitation • Newton developed this law by looking at the factors involved…whether they were proportional or not…and the amounts of the forces… he developed the following equation: • F a (m1xm2)/r2 • He realized he needed a constant to turn the proportion into an equation… • G=6.67x 10-11 Nxm2 /kg2

  3. See examples… • Ex 5-11 p126 • Ex 5-12 p127 • Ex 5-13 p127

  4. HW p141 25-28, 31-32
