Topics in Gravitation

1

Universal Law of Gravitation

  • Newton discovered that the same force causes apples to fall and moon to orbit Earth
  • Every object in the universe attracts every other object with gravitational force
  • Gravitational force is directly proportional to product of masses
2

Free Fall and Acceleration due to Gravity

  • Free fall occurs when objects fall under gravity alone (no air resistance)
  • All objects fall at same rate in vacuum regardless of mass
  • Acceleration due to gravity (g) = 9.8 m/s² near Earth's surface
3

Mass and Weight

  • Mass is measure of inertia and remains constant everywhere
  • Mass is amount of matter in an object
  • Weight is force with which Earth attracts an object
4

Thrust and Pressure

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