Unformatted text preview: Chapter 3 The Gravitational Interaction Challenge Exam: How to Prepare s Read the book s Learn the models, like Electrical model of matter Molecular model of matter Big bang model of the universe The different models of the atom The different models of the atom The nebular model of star formation s Focus on new concepts Cosmology Plate tectonics The geologic column s Answer all the questions at the end of each chapter Last Time s Force, acceleration, state of motion ewtons Laws s Newtons Laws Key Concepts 1. Motion of falling objects (no friction) 2. Understand projectile motion 3. Orbiting objects 4. Universal law of gravitation 5. Cavendishs gravity experiment 6. Physical interpretation of Einsteinian gravity Quiz When a fly hits your windshield, the reason the fly goes SPLAT! is because: a) The force on the fly is much greater than the force on the windshield, so the acceleration of the fly is much greater b) The mass of the windshield is much greater than the mass of the fly, so the acceleration of the fly is much greater. I have read chapter 3 A. Yes B. Sort of C. No, but I feel guilty bout it. about it. D. Didnt read, Dont care. Gravity s A force that causes a u n i f o r m acceleration when measured at Earths 1 sec. 1 sec. Force of Gravity Velocity Acceleration surface ....
