Topics in Gravitation

1

9.1 Universal Law of Gravitation

  • Every object in the universe attracts every other object with a gravitational force
  • Gravitational force is directly proportional to the product of masses of two objects
  • Gravitational force is inversely proportional to the square of distance between objects
2

9.2 Free Fall and Acceleration due to Gravity

  • Free fall occurs when objects move under Earth's gravitational force alone
  • All objects in free fall experience same acceleration regardless of mass
  • Acceleration due to gravity (g) = 9.8 m/s² near Earth's surface
3

9.3 Mass vs Weight

  • Mass is measure of inertia and amount of matter in an object
  • Mass remains constant everywhere in universe
  • Weight is gravitational force acting on an object
4

9.4 Thrust and Pressure

  • Thrust is force acting perpendicular to a surface
  • Pressure is thrust per unit area (P = F/A)
  • Same force on smaller area creates higher pressure
